Disseminated American muco-cutaneous leishmaniasis caused by Leishmania brasiliensis brasiliensis in a patient with AIDS: a case report

The authors report a case of culture-proven disseminated American muco-cutaneous leishmaniasis caused by Leishmania brasiliensis brasiliensis in an HIV positive patient. Lesions began in the oropharynx and nasal mucosa eventually spreading to much of the skin surface. The response to a short course of glucantime therapy was good.

Anomalous sub aortic left brachiocephalic vein: a case report

The left brachiocephalic vein occasionally follows an aberrant course. It is usually associated with congenital cardiac anomaly. We present a case of anomalous left brachiocephalic vein which followed a sub aortic course, with no cardiac abnormality. Multi detector computed tomography is very useful in accurate diagnosis of this condition and prevents any further investigation in cases of isolated abnormalities.

Schwannoma of the inferior turbinate: case report and review of literature

Schwannomas of the sinonasal tract are rare entities that are amenable to local resection. We present a 69 year old woman with a schwannoma of the inferior turbinate that was successfully resected. Schwannomas arising from the inferior turbinate are very infrequent.

Giant oesophageal liposarcoma: case report

We describe imaging findings of a oesophageal liposarcoma in a 66 year old man. The computed tomography scan was performed after a chest radiograph showed a large posterior mediastinal mass. Oesophageal liposarcomas are rare tumours. They can achieve large size before they become symptomatic. Our patient was successfully managed with complete surgical removal.

Posterior migration of lumbar disc herniation - imaging dilemma due to contrast contraindication: a case report

Disc herniation with posterior epidural migration is a rare and often symptomatic entity. Multiple are the natural barriers that prevent this pattern of migration. Enhanced magnetic resonance imaging is the diagnostic modality of choice in these cases. The diagnostic dilemma in this case was the contraindication to the use of contrast since the patient was known to have chronic renal failure.

Pelvic lipomatosis: a case report and literature review

Pelvic lipomatosis is a rare disorder where fat tissue deposition is observed in spaces of the pelvic area, causing extrinsic compression of the bladder, rectum and blood vessels. In the present report, the authors describe the case of a 48-year-old male patient presenting low back pain, dysuria and pollakiuria. Findings at excretory urography, computed tomography and magnetic resonance imaging are described.

Heterotaxy syndrome: a case report

The present report describes the findings at chest computed tomography angiography of a 28-year-old female patient with heterotaxy syndrome. This syndrome consists of a variety of anomalies of position and morphology of thoracoabdominal organs which do not follow the situs solitus or situs inversus arrangement. Imaging studies play a fundamental role in the individualization of the approach to the patient.

Persistence of stapedial artery: a case report

Persistent stapedial artery is a rare congenital anomaly that occurs by a failure in the involution of such artery. Most patients with persistent stapedial artery are asymptomatic. The imaging diagnosis is made principally by means of multidetector computed tomography. In the present case, persistent stapedial artery was an incidental computed tomography finding. The authors discuss the embryogenesis, computed tomography findings and the importance of an early diagnosis of such anomaly.

Bilateral Killian-Jamieson diverticula demonstrated by videofluoroscopic swallowing study: case report

The authors report the case of a 56-year-old male patient complaining of dysphagia for solids and food impaction, submitted to videofluoroscopic swallowing study that demonstrated the presence of two esophageal diverticula. The videofluoroscopic swallowing study was critical in the identification and diagnosis of the diverticula, an esophageal cause of dysphagia.

Giant cell tumor of the frontal sinus: case report

The authors report the case of a giant cell tumor of the frontal sinus in a 54-year-old male patient. This tumor location is rare, and this is the third case reported in the literature with radiographic documentation and histopathological confirmation. The patient underwent surgery, with curettage of frontal sinus and placement of a prosthesis. He died because a voluntary abrupt discontinuation of corticosteroids.

Frontal sinus pneumocele: case report and literature review

The authors report a rare case of frontal sinus pneumocele in a 26-year-old female patient assessed by computed tomography.

Brain metastasis as initial presentation of papillary adenocarcinoma of the lung: case report

The authors describe the case of a 33-year-old patient with history of seizures alone without any previous symptom, being diagnosed with brain metastases from primary papillary adenocarcinoma of the lung. Emphasis is given to the diagnostic investigation for brain metastasis and prognostic evaluation of papillary adenocarcinoma of the lung, and a brief literature review on such diseases is performed.

Pulmonary interstitial emphysema: a case report and review of the literature

Pulmonary interstitial emphysema is a rare condition that generally affects low-weight preterm infants submitted to mechanical ventilation. The prognosis is variable, depending on early diagnosis and treatment. The radiologist plays a key role in this scenario. The authors report a case of persistent pulmonary interstitial emphysema, describing the main characteristics of such entity.
