Translumbar inferior vena cava catheter for long-term hemodialysis.

Vascular access failure is a major cause of morbidity and even mortality in patients on chronic hemodialysis. The failure of conventional vascular access and thrombosis of the superior vena cava in a patient with ESRD was successfully treated by the percutaneous insertion of a hemodialysis catheter directly into the inferior vena cava. The translumbar access to the inferior vena cava has been used successfully in bone marrow transplant recipients and may also be used as a last choice for long-term hemodialysis when conventional access is difficult.

Breast metastasis from primary cervical cancer.

Metastasis to the breast from primary cervical cancer is rare. A 52-year-old woman developed breast metastasis 6 months after the diagnosis of primary cervical cancer. The mammography showed discrete well defined nodules without microcalcification. Fine needle aspiration cytology confirmed the diagnosis. Treatment with cis-platinum chemotherapy and local radiotherapy resulted in complete response. The patient continues to be alive and disease-free 18 months since the diagnosis of breast metastasis.

Giant thoracoabdominal lymphangioma with features of lymphangiomyoma.

A 15-year-old girl who presented with cough and dyspnea was found to have a mediastinal tumor that clinically resembled a lymphangioma. The tumor was unusual for its large size and its histologic features, which showed smooth muscle proliferation, generally considered a feature of lymphangiomyoma.

Noninvasive preoperative localization of an intracardiac bullet.

A 40-year-old patient with intracardiac gunshot injury is reported. The bullet was localized preoperatively within the pericardium at the junction of the right atrium and the inferior caval vein and was removed successfully at surgery. The role of various imaging techniques in the preoperative localization of intracardiac missiles is discussed.

Normal endoscopic pancreatogram in an Indian referral hospital.

A total of 101 normal pancreatograms were analysed in a major referral hospital in India in an attempt to establish normal standards of pancreatic ductal morphology in Indian population. Ductal position, course, caliber, length and variations of anatomy were analysed. Most often (39%) ampulla was seen at the level of second lumbar vertebra, commonly (54%) within 30-39 mm from the lateral margin of right side of corresponding vertebral body. Most common ductal course (21.78%) was ascending-horizontal-horizontal type. Mean ductal diameters in the head, body and tail of the pancreas were 2.63, 1.95, 0.99 mm in individuals aged less than or equal to 40 yr and 3.31, 2.34, 1.23 mm in those greater than 40 yr, respectively. A significant (r = 0.46; P less than 0.001) increase in ductal size was seen between less than or equal to 40 yr and after 40 yr of age. Mean ductal length was 16.10 and 16.58 cm in subjects less than or equal to 40 yr of age and greater than 40 yr respectively. Duct of Santorini was visualised in 6.6 per cent subjects.

Omental infarction: report of three cases and review of the literature.

Omental Infarction, the end result of impaired perfusion to the greater omentum, is a rare entity (JBCM Puylaert, Radiology 1992;185:169-172). We recently encountered three patients in whom computed tomography (CT) showed the characteristic findings of omental infarction. The diagnosis was subsequently confirmed intraoperatively and pathologically in two of the cases. The third case showed partial resolution on follow-up computed tomography. All three cases are presented with a brief review of the literature.

Hepatocellular carcinoma--image morphology in 40 patients.

A retrospective analysis of image morphology in 40 patients with histologically proved hepatocellular carcinoma including two cases of fibrolamellar carcinoma is presented. Ultrasound and CT scan were done in all the patients. Angiogram was done in 15 of these patients to provide a surgical roadmap before hepatic resection. Detailed analysis of clinical features, biochemical parameters and image morphology is presented.

Biliary cystadenoma mistaken as hydatid cyst.

First documented case of biliary cystadenoma in a non-white elderly female is described, showing (so called) low-density daughter cysts within the mother cyst emphasising the fact that presence of daughter cysts within a mother cyst cannot be considered pathognomonic of hepatic hydatid cyst.
