Kernohan's notch and misdiagnosis of disorders of consciousness.

A 69-year-old man presented with a sudden headache followed by unconsciousness. There was no head injury. The Glasgow Coma Scale (GCS) score was 3/15 and there was a left mydriasis, unreactive to light. The CT-scan showed a left acute subdural haematoma causing a remarkable mass effect. A supratentorial hemispheric craniotomy was performed. Nevertheless, after several weeks at the intensive care unit (ICU), the patient was still unresponsive to external stimuli and did not show any motor activity. A comfort care attitude was decided on with the family and the patient was extubated. However, a few days later, the patient subsequently showed a surprisingly favourable course, with improved wakefulness. Indeed, the GCS score improved, and the treatment plan was modified so that the patient benefited from rehabilitation. The MRI showed a right cerebral peduncle lesion, consistent with a Kernohan-Woltman notch phenomenon (KWNP). Six months later, the patient was able to walk and live quite normally.

Nontraumatic spinal epidural hematoma during pregnancy: diagnosis and management concerns.

OBJECTIVE: Nontraumatic spinal epidural hematoma (SEH) during pregnancy is rare. Therefore, appropriate management of this occurrence is not well defined. The aim of this study was to extensively review the literature on this subject, to propose some novel treatment guidelines. METHODS: Electronic databases, manual reviews and conference proceedings up to December 2011 were systematically reviewed. Articles were deemed eligible for inclusion in this study if they dealt with nontraumatic SEH during pregnancy. Search protocols and data were independently assessed by two authors. RESULTS: In all, 23 case reports were found to be appropriate for review. The mean patient age was 28 years and gestational age was 33.2 weeks. Thirteen cases presented with acute interscapular pain. The clinical picture consisted of paraplegia, which occurred approximately 63 h after pain onset. Spinal cord decompression was performed within an average time of 20 h after neurological deficit onset. Fifteen patients had cesarean deliveries, even when the gestational age was less than 36 weeks. CONCLUSION: This review failed to identify articles, other than case reports, which could assist in the formation of new guidelines to treat SEH in pregnancy. However, we believe that SEH may be managed neurosurgically, without requiring prior, premature, cesarean section.

Clinically silent subdural hemorrhage causes bilateral vocal fold paralysis in newborn infant.

Bilateral congenital vocal fold paralysis (BVFP) may result from multiple etiologies or remain idiopathic when no real cause can be identified. If obstructive dyspnea is significant and requires urgent stabilization of the airway, then intubation is performed first and an MRI of the brain is conducted to rule out an Arnold-Chiari malformation that can benefit from a shunt procedure and thus alleviate the need for a tracheostomy. Clinically silent subdural hemorrhage without any birth trauma represents another cause of neonatal BVFP that resolves spontaneously within a month. It is of clinical relevance to recognize this potential cause of BVFP as its short duration may alleviate the need for a tracheostomy. In this article, we present such a case and review the literature to draw the otolaryngologist's attention to this possible etiology.

Spinal epidural hematoma: not always an obvious diagnosis.

Spinal epidural hematoma (SEH) is a rare neurosurgical emergency. SEH is characterized by an archetypal clinical presentation including abrupt spinal pain followed more or less rapidly by various degrees of neurological deficit. The diagnosis of SEH, often based on a clinical presumption, represents a clinical challenge. Several reports have outlined missed or delayed diagnosis due to unusual and confusing onsets or unawareness of this diagnosis by physicians. Therefore, physicians should keep in mind the possibility of SEH in their differential diagnosis when confronted with patients complaining of sudden onset of acute spinal pain with or without neurological sign, because the impact of a delayed diagnosis can be disabling catastrophic neurological sequelae. We suggest that SEH is a dynamic disease, which occurs in patients with an abnormal vasculature structural degenerative change. The bleeding is probably of multifactorial origin incriminating veins as well as arteries. Therefore, we proposed a classification of SEH, according to the most probable etiology whatever the associated factors, in six groups: spontaneous, secondary, iatrogenic, traumatic, recurrent, and idiopathic SEH.

Hematoma intraparenquimatoso cerebral espontâneo: aspectos à tomografia computadorizada

OBJETIVO: Identificar os aspectos mais freqüentes do hematoma intraparenquimatoso cerebral espontâneo observados na tomografia computadorizada. MATERIAIS E MÉTODOS: Foram analisados, retrospectivamente, os exames de tomografia computadorizada de 250 pacientes com hematoma intraparenquimatoso cerebral espontâneo, provenientes de três diferentes hospitais da cidade do Rio de Janeiro. RESULTADOS: O hematoma intraparenquimatoso cerebral profundo foi o de maior incidência, equivalendo a 54,4% (136 casos), seguido do lobar com 34,8% (87 casos). Mais raramente, observou-se sangramento cerebelar em 8,4% (21 casos) e do tronco cerebral em 2,4% (seis casos) dos pacientes. CONCLUSÃO: A cefaléia foi o sintoma mais comum e a hipertensão arterial foi o sinal mais freqüentemente apresentado. A drenagem do hematoma para o sistema ventricular ocorreu mais comumente nos hematoma profundos.

Obstrução duodenal por hematoma parietal pós-trauma: relato de caso e revisão da literatura

Os hematomas parietais de alças intestinais por trauma abdominal fechado, determinando rápida obstrução luminal, são lesões raras e podem ser confundidas com afecções neoplásicas estenosantes (parietais ou por mecanismo de compressão extrínseca). Neste estudo é relatado um caso de obstrução intestinal por hematoma parietal da terceira porção duodenal pós-trauma e são discutidos o diagnóstico por imagem e o tratamento para tal obstrução.

Hematoma renal en paciente monorreno: caso clínico

Descrito en 1856 por Wunderlich, el hematoma perirrenal espontáneo es una patología infrecuente, en la que a pesar de llegar al diagnóstico de una manera relativamente sencilla con estudios imagen, el poder determinar la etiología representa un reto y es motivo de múltiples estudios y procedimientos invasivos, algunas veces sin poder llegar a esclarecer la causa1. Los hematomas renales y esplénicos están asociados con frecuencia a traumatismos abdominales y más raramente se deben a alteraciones de la coagulación e infecciones. Otras causas menos frecuentes son procesos inflamatorios, diátesis sanguínea,...

Retenção urinária aguda por extenso hematoma pelvico após herniorrafia inguinal

The authors report a rare case of a patient with urinary retention following an inguinal herniorraphy, due to extrinsic compression of the bladder by an extensive pelvic hematoma, diagnosed by cystourethrogram and pelvic computadorized tomography. A medical treatment was provided by vesical catheterization for seven days. After this period of time, the hematoma had disappeared and the patient recovered to spontaneous miction.

Hematoma retroperitoneal espontâneo

We present a case of a spontaneous retroperitoneal hematoma in a 62 year-old man who was using acethylsalicylic acid (ASA). Spontaneous retroperitoneal hematoma is a rare, but potentially serious complication of anticoagulation therapy. Through literature revision, we have discussed the etiological aspects of this disease and the importance of obtaining the preoperative diagnosis for an appropriate and conservative operative treatment.

Hematoma espontâneo do músculo reto abdominal

Spontaneous hematoma of the rectus sheath is a rare entity, which may be confused with the surgical causes of acute abdomen. We present a well succeeded conservative therapy in a woman in the 7th decade of life.

Análise epidemiológica de 210 casos de hematoma extradural traumático tratados cirurgicamente

OBJETIVO: Analisar aspectos da epidemiologia, apresentação clínica e radiológica de pacientes com hematoma extradural traumático (HED) submetidos a procedimento neurocirúrgico. MÉTODOS: Foi realizada a revisão de prontuários de 210 pacientes admitidos no Serviço de Emergência com HED diagnosticados através de tomografia computadorizada, tratados cirurgicamente no período de agosto de 1998 a janeiro de 2008. Foram analisados: idade, sexo, apresentação clínica e radiológica, mecanismo de trauma e status neurológico no momento da alta hospitalar. RESULTADOS: Em 49,2% o mecanismo de trauma foi queda; 89,2% dos pacientes eram do gênero masculino; 49,7% dos casos tinham Escala de Coma de Glasgow (ECG) entre 13-15; 61% dos pacientes tinham idade entre 20-49 anos; A localização do HED em 26,5% e 19,6% dos casos foi têmporo-parietal e temporal, respectivamente; 32,8% tinham lesões intracranianas associadas, sendo a fratura craniana evidenciada em cerca de 45% dos casos; 76,2% dos pacientes tratados cirurgicamente tiveram alta com déficit mínimo ou ausência de déficit neurológico. CONCLUSÃO: Observamos que o HED, na população de estudo, apresenta-se mais frequentemente no gênero masculino, na quarta década de vida, mais relacionado às quedas. Na admissão, observamos uma ECG entre 13 e 15, sendo pertinente mencionar o envolvimento da região têmporo-parietal na maioria dos casos. Acreditamos que o conhecimento da epidemiologia do hematoma extradural traumático pode auxiliar na elaboração de medidas de saúde pública, visando à prevenção e identificação precoce desta doença em determinada população.

Atenolol prevents the formation of expansive hematoma after rhytidoplasty

Objective: To evaluate the perioperative use of atenolol in reducing the incidence of hematoma after rhytidoplasty.Methods: Between January 2007 and February 2013, 80 patients were randomized into two groups: Group A (n = 26) received perioperative atenolol in order to maintain heart rate (PR) around 60 per minute; Group B (n = 54) did not receive atenolol. Both groups underwent the same anesthetic and surgical technique. We monitored blood pressure (BP), HR, hematoma formation and the need for drainage. Patients were followed-up until the 90th postoperative day. The variables were compared between the groups using the ANOVA test. Continuous variables were presented as mean ± standard deviation and the differences were compared with the Student's t test. Values of p d" 0.05 were considered significant.Results: In group A the mean BP (110-70mmHg ± 7.07) and HR (64 / min ± 5) were lower (p d" 0.05) than in group B (135-90mmHg ± 10.6) and (76 / min ± 7.5), respectively. There were four cases of expansive hematoma in group B, all requiring reoperation for drainage, and none in group A (p d" 0,001).Conclusion: The perioperative use of atenolol caused a decrease in blood pressure and heart rate and decreased the incidence of expanding hematoma after rhytidectomy.
