Recurrence After Operative Management of Intrahepatic Cholangiocarcinoma

INTRODUCTION: Data on recurrence after operation for intrahepatic cholangiocarcinoma (ICC) are limited. We sought to investigate rates and patterns of recurrence in patients after operative intervention for ICC. METHODS: We identified 301 patients who underwent operation for ICC between 1990 and 2011 from an international, multi-institutional database. Clinicopathologic data, recurrence patterns, and recurrence-free survival (RFS) were analyzed. RESULTS: During the median follow up duration of 31 months (range 1-208), 53.5% developed a recurrence. Median RFS was 20.2 months and 5-year actuarial disease-free survival, 32.1%. The most common site for initial recurrence after operation of ICC was intrahepatic (n = 98; 60.9%), followed by simultaneous intra- and extrahepatic disease (n = 30; 18.6%); 33 (21.0%) patients developed extrahepatic recurrence only as the first site of recurrence. Macrovascular invasion (hazard ratio [HR], 2.08; 95% confidence interval [CI], 1.34-3.21; P < .001), nodal metastasis (HR, 1.55; 95% CI, 1.01-2.45; P = .04), unknown nodal status (HR, 1.57; 95% CI, 1.10-2.25; P = .04), and tumor size ≥5 cm (HR, 1.84; 95% CI, 1.28-2.65; P < .001) were independently associated with increased risk of recurrence. Patients were assigned a clinical score from 0 to 3 according to the presence of these risk factors. The 5-year RFS for patients with scores of 0, 1, 2, and 3 was 61.8%, 36.2%, 19.5%, and 9.6%, respectively. CONCLUSION: Recurrence after operative intervention for ICC was common. Disease recurred both at intra- and extrahepatic sites with roughly the same frequency. Factors such as lymph node metastasis, tumor size, and vascular invasion predict highest risk of recurrence.

A 63-Year-Old Woman Presenting with a Synovial Sarcoma of the Hand: a Case Report

INTRODUCTION: Synovial sarcoma is a high-grade, soft-tissue sarcoma that most frequently is located in the vicinity of joints, tendons or bursae, although it can also be found in extra-articular locations. Most patients with synovial sarcoma of the hand are young and have a poor prognosis, as these tumors are locally aggressive and are associated with a relatively high metastasis rate. According to the literature, local recurrence and/or metastatic disease is found in nearly 80% of patients. Current therapy comprises surgery, systemic and limb perfusion chemotherapy, and radiotherapy. However, the 5-year survival rate is estimated to be only around 27% to 55%. Moreover, most authors agree that synovial sarcoma is one of the most commonly misdiagnosed malignancies of soft tissues because of their slow growing pattern, benign radiographic appearance, ability to change size, and the fact that they may elicit pain similar to that caused by common trauma. CASE PRESENTATION: We describe an unusual case of a large synovial sarcoma of the hand in a 63-year-old Caucasian woman followed for 12 years by a multidisciplinary team. In addition, a literature review of the most pertinent aspects of the epidemiology, diagnosis, treatment and prognosis of these patients is presented. CONCLUSION: Awareness of this rare tumor by anyone dealing with hand pathology can hasten diagnosis, and this, in turn, can potentially increase survival. Therefore, a high index of suspicion for this disease should be kept in mind, particularly when evaluating young people, as they are the most commonly affected group.

Carcinoma Oculto da Mama com Metástases Axilares. A Propósito de Dois Casos Clínicos

INTRODUÇÃO: O carcinoma oculto é uma entidade pouco frequente, que se define como a presença de metástases com tumor primário indetetável na altura da apresentação. O prognóstico da maioria dos casos de tumor oculto é reservado, no entanto, o desenvolvimento de técnicas imunohistoquímicas que permitem a caracterização do tumor, tornaram alguns subgrupos de tumor oculto potencialmente curáveis. A presença de adenopatias axilares é a forma de apresentação do cancro da mama em 0,3-1% das mulheres, sendo a origem mais provável a mama ipsilateral. CASO CLÍNICO: Os autores relatam dois casos clínicos de tumor oculto da mama: Caso 1: Doente de 57 anos, com antecedentes familiares de primeiro e segundo grau de cancro da mama, com estudo genético negativo. Recorreu à consulta por adenopatia axilar direita.Exame objetivo (EO), mamografia + ecografia mamária normais. Microbiópsia (MB) ganglionar:metástase de carcinoma compatível com origem na mama, recetores de estrogénios (RE) +, HER2 +, CK7 +, Ca125 +, CK20 (-). RMN mamária e PET não identificaram tumor primário. Procedeu-se a dissecção axilar: 10 gânglios sem metástases. Realizou terapêutica adjuvante com quimioterapia (QT) e imunoterapia (IT). Manteve follow-up regular com EO, RMN e mamografia alternadas até aos 4 anos sem alterações. Aos 4,5 anos detetou-se ao E.O. nódulo palpável na mama direita e nódulo axilar. Mamografia + ecografia: lesão sólida suspeita (R5) cuja caracterização histológicademonstrouCDIG3, recetores hormonais (-) (RH), HER2 3+, Ki67 >30%. A TC TAP e a cintigrafia óssea não revelaram alterações. Em reunião multidisciplinar de decisão terapêutica (RMDT) decidiu-serealizar mastectomia total direita + mastectomia profilática contralateral com reconstrução. Exame histológico:CDI G3 com 22mm,confirmando-se a caracterização imunohistoquímica, com invasão vascular e presença de 3 gânglios com metástase e extensão extracapsular (T2 N2). Realizou terapêutica adjuvante com QT + IT+ Radioterapia (RT) da parede torácica e ganglionar. Um ano após a mastectomia, a doente mantém-se em follow-up sem sinais de recidiva. Caso 2: Doente de 50 anos, com antecedentes familiares de primeiro grau de cancro da mama. Recorreu à consulta por nódulo da axila esquerda e nódulo da mama direita com 2 meses de evolução. EO: nódulo palpável da mama direita e duas adenopatias axilares à esquerda. Mamografia + eco: microcalcificações atípicas da mama esquerda (R5) ealterações benignas da mama direita (R2). Realizaram-se microbiópsia por estereotaxia e biópsia assistida por vácuo da mama esquerda e citologia aspirativa de agulha fina (CAAF) de nódulo da mama direita:sem alterações neoplásicas. A biópsia de adenopatia axilar revelou metástase ganglionar de carcinoma compatível com origem na mama, RH (-), GCDFP15 (-),HER2 3+ e CK7 +.A RM mamária revelou apenas lesões benignas. TC TAP, ecografia abdominal e cintigrafia óssea normais. PET: lesão localizada na axila esquerda, nos três níveis axilares. Por recusa da doente em realizar microbiópsias adicionais ou mastectomia radical modificada, optou-se por realizar dissecção axilar esquerda. Exame histológico: 7 em 14 gânglios com metástases, morfologia e estudo imunohistoquímico concordantes com o anterior. Em RMDT foi decidida terapêuticaadjuvante com RT, QT e IT que a doente se encontra no momento a realizar. DIAGNÓSTICOS DIFERENCIAIS/ DISCUSSÃO A presença de adenopatias axilares relaciona-se na maioria dos casos com processos benignos, mas naqueles em que se diagnostica uma neoplasia maligna, mais de 50% correspondem a carcinoma da mama. Outras neoplasias que se podem apresentar com metástases axilares são: linfoma, melanoma, sarcoma, tiróide, pulmão, estômago, ovário, útero. A avaliação diagnóstica deve incluir além do exame físico, a biópsia ganglionar (para exame histológico e caracterização imunohistoquímica), mamografia, ecografia mamária e ressonância magnética mamária, eventual TC toraco-abdominal, cintigrafia óssea nas mulheres sintomáticas, existindo controvérsia sobre autilidade da PET. CONCLUSÕES O tumor oculto representa um problema diagnóstico e um desafio terapêutico. O carcinoma da mama apresentando-se sob a forma de metástase axilar sem tumor primário identificável e sem doença à distância, considera-se um dos casos potencialmente curáveis, se for tratado de acordo com as guidelines para o estadio II do cancro da mama. A abordagem recomendada inclui dissecção axilar, de importância crucial pela informação prognóstica que guiará o restante tratamento e por ajudar no controlo local da doença. A terapêutica adequada da mama ipsilateral é controversa, e pode passar pela mastectomia radical modificada ou RT. Não existem até à data estudos randomizados comparando a mastectomia versus RT mamária e os estudos retrospetivos disponíveis não apresentam resultados consensuais. A decisão de RT da parede torácica pós-mastectomia e de terapêutica adjuvante deverá ser tomada tendo em conta as guidelines publicadas.

The Oncological and Functional Risks of the Organ Preservation Experimental Treatment Approach

We increasingly face conservative surgery for rectal cancer and even the so called ‘wait and see’ approach, as far as 10–20% patients can reach a complete pathological response at the time of surgery. But what can we say to our patients about risks? Standard surgery with mesorectal excision gives a <2% local recurrence with a post operative death rate of 2–8% (may reach 30% at 6 months in those over 85), but low AR has some deterioration in bowel function and in low cancer a permanent stoma may be required. Also a long-term impact on urinary and sexual function is possible. Distant metastasis rate seem to be identical in the standard and conservative approach. It is difficult to evaluate conservative approach because a not clear standardization of surgery for low rectal cancer. Rullier et al tried to clarify, and they found identical results for recurrence (5–9%), disease free survival (70%) at 5y for coloanal anastomosis and intersphinteric resection. Other series have found local recurrence higher than with standard approach and functional results may be worse and, in some situations, salvage therapy is compromised or has more complications. In this context, functional outcomes are very important but most studies are incomplete in measuring bowel function in the context of conservative approach. In 2005 Temple et al made a survey of 122/184 patient after sphinter preserving surgery and found a 96.9% of incomplete evacuation, 94.4% clustering, 93.2% food affecting frequency, 91.8% gas incontinence and proposed a systematic evaluation with a specific questionnaire. In which concerns ‘Wait and see’ approach for complete clinical responders, it was first advocated by Habr Gama for tumors up to 7cm, with a low locoregional failure of 4.6%, 5y overall survival 96%, 72% for disease free survival; one fifth of patients failed in the first year; a Dutch trial had identical results but others had worse recurrence rates; in other series 25% of patients could not be salvaged even with APR; 30% have subsequent metastatic disease what seems equal for ‘wait and see’ and operated patients. In a recent review Glynne Jones considers that all the evaluated ‘wait and see’ studies are heterogeneous in staging, inclusion criteria, design and follow up after chemoradiation and that there is the suggestion that patients who progress while under observation fare worse than those resected. He proposes long-term observational studies with more uniform inclusion criteria. We are now facing a moment where we may be more aggressive in early cancer and neoadjuvant treatment to be more conservative in the subsequent treatment but we need a better stratification of patients, better evaluation of results and more clear prognostic markers.

Understanding Cardiac Myxoma Recurrence: A Case Report

Recurrence of cardiac myxoma is a rare condition, observed in about 3% of patients in sporadic cases, although it is more frequent in familial ones. Several mechanisms have been proposed to explain such recurrence, and the importance of increased vascularization as a facilitating feature is the subject of debate. The authors report the case of a non-familial right atrial myxoma, unusual for both its histopathology and recurrence.

Post-Treated Prostate Cancer: Normal Findings and Signs of Local Relapse on Multiparametric Magnetic Resonance Imaging

The use of multiparametric magnetic resonance imaging (mp-MRI) for prostate cancer has increased over recent years, mainly for detection, staging, and active surveillance. However, suspicion of recurrence in the set of biochemical failure is becoming a significant reason for clinicians to request mp-MRI. Radiologists should be able to recognize the normal post-treatment MRI findings. Fibrosis and atrophic remnant seminal vesicles after prostatectomy are often found and must be differentiated from local relapse. Moreover, brachytherapy, external beam radiotherapy, cryosurgery, and hormonal therapy tend to diffusely decrease the signal intensity of the peripheral zone on T2-weighted images (T2WI) due to the loss of water content, consequently mimicking tumor and hemorrhage. The combination of T2WI and functional studies like diffusion-weighted imaging and dynamic contrast-enhanced improves the identification of local relapse. Tumor recurrence tends to restrict on diffusion images and avidly enhances after contrast administration either within or outside the gland. The authors provide a pictorial review of the normal findings and the signs of local tumor relapse after radical prostatectomy, external beam radiotherapy, brachytherapy, cryosurgery, and hormonal therapy.

Long-Term Recurrence of Nonmelanoma Skin Cancer after Topical Methylaminolevulinate Photodynamic Therapy in a Dermato-Oncology Department

BACKGROUND: Most available studies on the efficacy of topical photodynamic therapy focus on short-to medium-term results. Long-term data are scarce. OBJECTIVE: To evaluate the long-term efficacy of photodynamic therapy with topical methylaminolevulinate to treat Bowen's disease and basal cell carcinoma in the clinical practice setting of a dermato-oncology department. METHODS: The study included patients diagnosed with Bowen's disease or basal cell carcinoma, and who received photodynamic therapy from 2004 to 2008. Treatment protocol and clinical follow-up were standardized. The primary endpoint was clinically observed recurrence in a previous photodynamic therapy-treated area. Descriptive and survival analyses were performed. RESULTS: A total of 31 Bowen's disease lesions and 44 superficial basal cell carcinoma were treated, with a median follow-up of 43.5 months. Recurrence was observed in 14 Bowen's disease lesions (53.8%) and in 11 superficial basal cell carcinoma (33.3%). Significantly higher estimates for recurrence rates were found in patients with Bowen's disease (p=0.0036) or those aged under 58 years (p=0.039). The risk of recurrence was higher in patients with Bowen's disease than in those with superficial basal cell carcinoma and younger patients. CONCLUSIONS: Recurrence should be considered when choosing to treat non-melanoma skin cancer with photodynamic therapy. Younger age and Bowen's disease were independent predictors for long-term recurrence, suggesting the need to establish an extended period of follow-up for this subset of patients.

Tumores do Corpo Carotídeo. Experiência de um Serviço no Diagnóstico e Tratamento nos Últimos 10 Anos

INTRODUCTION: Carotid body tumours (CBT) are neoplasms that develop from paragangionic cells of this structure. They are rare, with an estimated incidence of 1:30000 and can be associated with other neuro-endocrine neoplasia. The authors report their experience in the management of the disease, in the last 10 years. MATERIAL AND METHODS: Eight patients (with eight tumours) were treated, all submitted to tumour resection. 75% were female and the mean age was 56 years. We report a 12,5% incidence of neurological sequelae from surgery, and no mortality. In the follow-up (which varied between 1 and 10 years), no local or contralateral recurrence or metastasis were registered. Also, we did not found family cases of this disease. CONCLUSIONS: The authors noticed an unusually high proportion of female patients. The tumour resection was curative in all patients, with a rate of neurological complications inferior to that reported in other published series. These neurological sequelae were reported in patients with large tumours, thus reinforcing the outmost importance of an early diagnosis. Pre-operative selective embolization of these tumours can be helpful in the resection of large tumours, allowing a potential reduction in neurological complications.

Derrame Pleural Revelador de Recidiva de Carcinoma Adenoquístico do Palato

Os autores apresentam um caso clínico de derrame pleural direito, num doente do sexo feminino com 68 anos de idade, surgindo fora do contexto de patologia cardiovascular ou infecciosa previamente conhecida. O diagnóstico final foi de neoplasia pleural secundária a carcinoma adenoquístico, com localização primitiva no palato duro, diagnosticado e tratado 8 anos antes, e que nunca apresentara recidiva local. Salienta-se a raridade deste diagnóstico e o facto de que, estando descrita a metastização pulmonar com possível envolvimento secundário da pleura, é muito raro o aparecimento de metástase pleural isolada.

Effects of Acute Autonomic Modulation on Atrial Conduction Delay and Local Electrograms Duration in Paroxysmal Atrial Fibrillation

Slowed atrial conduction may contribute to reentry circuits and vulnerability for atrial fibrillation (AF). The autonomic nervous system (ANS) has modulating effects on electrophysiological properties. However, complex interactions of the ANS with the arrhythmogenic substrate make it difficult to understand the mechanisms underlying induction and maintenance of AF. AIM: To determine the effect of acute ANS modulation in atrial activation times in patients (P) with paroxysmal AF (PAF). METHODS AND RESULTS: 16P (9 men; 59±14years) with PAF, who underwent electrophysiological study before AF ablation, and 15P (7 men; 58±11years) with atrioventricular nodal reentry tachycardia, without documentation or induction of AF (control group). Each group included 7P with arterial hypertension but without underlying structural heart disease. The study was performed while off drugs. Multipolar catheters were placed at the high right atrium (HRA), right atrial appendage (RAA), coronary sinus (CS) and His bundle area (His). At baseline and with HRA pacing (600ms, shortest propagated S2) we measured: i) intra-atrial conduction time (IACT, between RAA and atrial deflection in the distal His), ii) inter-atrial conduction time (interACT, between RAA and distal CS), iii) left atrial activation time (LAAT, between atrial deflection in the distal His and distal CS), iv) bipolar electrogram duration at four atrial sites (RAA, His, proximal and distal CS). In the PAF group, measurements were also determined during handgrip and carotid sinus massage (CSM), and after pharmacological blockade of the ANS (ANSB). AF was induced by HRA programmed stimulation in 56% (self-limited - 6; sustained - 3), 68.8% (self-limited - 6; sustained - 5), and 50% (self-limited - 5; sustained - 3) of the P, in basal, during ANS maneuvers, and after ANSB, respectively (p=NS). IACT, interACT and LAAT significantly lengthened during HRA pacing in both groups (600ms, S2). P with PAF have longer IACT (p<0.05), a higher increase in both IACT, interACT (p<0.01) and electrograms duration (p<0.05) with S2, and more fragmented activity, compared with the control group. Atrial conduction times and electrograms duration were not significantly changed during ANS stimulation. Nevertheless, ANS maneuvers increased heterogeneity of the local electrograms duration. Also, P with sustained AF showed longer interACT and LAAT during CSM. CONCLUSION: Atrial conduction times, electrograms duration and fractionated activity are increased in PAF, suggesting a role for conduction delays in the arrhythmogenic substrate. Acute vagal stimulation is associated with prolonged interACT and LAAT in P with inducible sustained AF and ANS modulation may influence the heterogeneity of atrial electrograms duration.

Infecções Urinárias e Gravidez - Diagnóstico, Terapêutica e Prevenção

Objectives: Literature review of classification, epidemiology, pathophysiology, microbiology, clinical presentation, diagnosis, complications, treatment and prevention of urinary tract infections (UTI) in pregnancy. Data Sources and Review Methods: Bibliographic research in Medline, through PubMed and Medscape, of systematic reviews, observational studies, clinical guidelines, meta-analyses and randomized controlled trials published between January 1992 and December 2010. Results: Asymptomatic bacteriuria occurs in 2 to 10% of pregnant women, 30% of which will develop acute pyelonephritis if left untreated. Treatment of asymptomatic bacteriuria has been shown to reduce the risk of pyelonephritis in pregnancy. Therefore, screening and treatment of this form of UTI has become a standard of obstetrical care, although the ideal duration of the treatment is still controverse. Acute pyelonephritis is one of the most common medical complications of pregnancy and may be associated with maternal, obstetric and perinatal complications. There is no clear consensus in the literature regarding antibiotic choice or duration of therapy for symptomatic UTI. Increasing antibiotic resistance complicates the choice of empirical regimens and local resistance rates need to be taken into account when deciding the therapy. Considering the high rate of recurrence of UTI during pregnancy, prophylactic measures need to be taken in pregnant women who have already experienced UTI during their current pregnancy. Conclusions: Although UTI is a generally benign condition in non-pregnant women, it may be a potentially serious complication during pregnancy. Early diagnosis and treatment of UTI during pregnancy are mandatory and can prevent severe maternal and perinatal complications.

Long-Term Evaluation of Recurrence after Photodynamic Therapy with Topical Methyl Aminolevulinate for Non-Melanoma Skin Cancer: a Hospital-Based Study

Introduction & Objectives: Several factors may influence the decision to pursue nonsurgical modalities for the treatment of non-melanoma skin cancer. Topical photodynamic therapy (PDT) is a non-invasive alternative treatment reported to have a high efficacy when using standardized protocols in Bowen’s disease (BD), superficial basal cell carcinoma (BCC) and in thin nodular BCC. However, long-term recurrence studies are lacking. The aim of this study was to evaluate the long-term efficacy of PDT with topical methylaminolevulinate (MAL) for the treatment of BD and BCC in a dermato-oncology department. Materials & Methods: All patients with the diagnosis of BD or BCC, treated with MAL-PDT from the years 2004 to 2008, were enrolled. Treatment protocol included two MAL-PDT sessions one week apart repeated at three months when incomplete response, using a red light dose of 37-40 J/cm2 and an exposure time of 8’20’’. Clinical records were retrospectively reviewed, and data regarding age, sex, tumour location, size, treatment outcomes and recurrence were registered. Descriptive analysis was performed using chi square tests, followed by survival analysis with the Kaplan-Meier and Cox regression models. Results: Sixty-eight patients (median age 71.0 years, P25;P75=30;92) with a total of 78 tumours (31 BD, 45 superficial BCC, 2 nodular BCC) and a median tumour size of 5 cm2 were treated. Overall, the median follow-up period was 43.5 months (P25;P75=0;100), and a total recurrence rate of 33.8% was observed (24.4 % for BCC vs. 45.2% for BD). Estimated recurrence rates for BCC and BD were 5.0% vs. 7.4% at 6 months, 23.4% vs. 27.9% at 12 months, and 30.0% vs. 72.4% at 60 months. Both age and diagnosis were independent prognostic factors for recurrence, with significantly higher estimated recurrence rates in patients with BD (p=0.0036) or younger than 58 years old (p=0.039). The risk of recurrence (hazard ratio) was 2.4 times higher in patients with BD compared to superficial BCC (95% CI:1.1-5.3; p=0.033), and 2.8 times higher in patients younger than 58 years old (95% CI:1.2-6.5; p=0.02). Conclusions: In the studied population, estimated recurrence rates are higher than those expected from available literature, possibly due to a longer follow-up period. To the authors’ knowledge there is only one other study with a similar follow-up period, regarding BCC solely. BD, as an in situ squamous cell carcinoma, has a higher tendency to recur than superficial BCC. Despite greater cosmesis, PDT might no be the best treatment option for young patients considering their higher risk of recurrence.

Vigilância Epidemiológica de Infecção do Local Cirúrgico. Pós-Alta Hospitalar em Cirurgia de Ambulatório

A Infecção do Local Cirúrgico (ILC) é referida em vários estudos como a mais importante causa de complicações pós-operatórias no utente cirúrgico. A realização de um maior número de cirurgias em ambulatório poderá dificultar o processo de monitorização da ILC, fazendo com que os serviços que não possuam um eficaz programa de vigilância destas infecções, tenham taxas de infecção sub-notificadas. Neste contexto, e durante a frequência do Curso de Especialidade em Enfermagem Médico-Cirúrgica, na Universidade Católica Portuguesa de Lisboa, realizou-se um estágio na Comissão de Controle de Infeção (CCI) do Hospital Santo António dos Capuchos, durante o qual foi desenvolvido um projecto com o objectivo de: “planear um sistema de monitorização da infecção do local cirúrgico após alta hospitalar em cirurgia de ambulatório”. Neste projecto a monitorização das ILC é realizada pelos enfermeiros da Unidade de Cirurgia de Ambulatório, com a colaboração de um cirurgião de referência. A monitorização inclui três fases, sendo que na primeira realiza-se uma colheita de dados no processo dos utentes e na segunda fase é feita uma avaliação/triagem de sinais e sintomas de ILC, através de um contacto telefónico com os utentes ao 7º e 30º dia de pós-operatório e ao 365º dia nas cirurgias em que tenha sido feita colocação de prótese. Na terceira fase faz-se uma análise e discussão dos dados. Sempre que se considerar necessário é feita observação direta do local cirúrgico. Para a recolha de dados foram construídas quatro grelhas com indicadores. No período de 10 de Novembro a 17 Dez de 2011 foram monitorizados 19 utentes, entre os quais 2 desenvolveram sinais e sintomas compatíveis com ILC, com necessidade de se iniciar antibioterapia. Tendo em conta os quatro princípios básicos da profilaxia de infecções do local cirúrgico e pelo confronto com a informação que foi possível aferir ao longo da elaboração do projecto, considerou-se fundamental discutir com a equipa algumas sugestões de melhoria nos cuidados prestados, bem como a discussão de medidas para a implementação de um efectivo “Programa de VE de ILC numa UCA”.

Iatrogenic Aortic Pseudoaneurysm: a Forgotten Complication

Pseudoaneurysms of the ascending aorta are a rare complication of cardiac surgery. However, the poor prognosis associated with this condition if untreated makes early diagnosis and treatment important. We present the case of a 66-year-old woman who had undergone mitral valvuloplasty 12 days previously, who was admitted with a diagnosis of new-onset atrial fibrillation. The transthoracic echocardiogram showed a clot in the right atrium and anticoagulation was initiated, followed by antibiotic therapy. After further investigation, the patient was diagnosed with a pseudoaneurysm of the ascending aorta and underwent surgical repair, followed by six weeks of antibiotic therapy. She was readmitted six months later for an abscess of the lower sternum and mediastinum. After a conservative approach with antibiotics and local drainage failed, recurrence of a large pseudoaneurysm compressing the superior vena cava was documented. A third operation was performed to debride the infected tissue and to place an aortic allograft. There were no postoperative complications.
