Portal vein stenosis following living donor liver transplant: manifestations and management.

Improving outcome of liver resection in patients with colorectal metastases.

A 55-year-old man presented with a liver mass that had been diagnosed on ultrasonography, carried out in response to the patient's complaint of non-specific abdominal pain. Triphasic computed tomography (CT) revealed a lesion involving segments 1, 4, 5 and 8 of the liver. It was centrally hypodense with peripheral enhancement in the arterial phase suggesting a cholangiocarcinoma. The middle hepatic vein was encased and the tumour was present near the junction of the left hepatic and middle hepatic veins. We planned a right hepatic trisegmentectomy including resection of the caudate lobe but since the estimated volume of the liver remnant was only 17% of the total, we first embolised the right portal vein. CT scan repeated 5 weeks later revealed that the lesion was still resectable and that the left lateral segment had hypertrophied to 27% of the liver volume. We performed a right trisegmentectomy including caudate lobe resection using intra-operative ultrasonography to establish that the left hepatic vein was not involved. The removed lesion was hard with ill-defined margins. Histopathological examination revealed a hemangioma.

Liver hemangioma mimicking cholangiocarcinoma--a diagnostic dilemma.

Adrenal lipoma complicated by perinephric abscess.

A 10-yr-old girl presented with a seven-month history of upper abdominal discomfort and weight loss. Physical examination revealed an abdominal lump in the right hypochondrium and epigastrium. Ultrasound examination and a computerized tomographic scan showed a large lobulated mass arising from segments I, 1V, and VIII of liver with arteriovenous shunting and multiple small masses in segments VI and VII. An initial diagnosis of hemangioendothelioma with metastasis was made elsewhere following which she received chemotherapy. She had persistent abdominal discomfort because of which she became dependent on narcotics. The patient had fever because of tumor necrosis and also developed peripheral neuropathy. Finally, owing to progressively worsening of symptoms, she underwent left lobe living donor liver transplantation. Histopathological examination showed the mass to be a cavernous hemangioma, and the patient is now well.

Living donor liver transplantation for giant cavernous hemangioma of liver in a child.

Blunt abdominal trauma, acute mesenteric venous thrombosis and small bowel stricture.

Malignant masquerade at the hepatic hilum.

We present a case of primary esophageal tuberculosis presenting as solitary submucosal mass in cervical esophagus with clinical features of dysphagia, thus mimicking a submucosal leiomyoma on imaging in a 39 year old lady. Excision of this mass revealed features suggestive of tuberculosis on histopathology.
