Torsion of pedunculated hepatocellular carcinoma. Report of a case in a young woman presenting with abdominal pain.

Pedunculated Hepatocellular Carcinoma is an extremely rare neoplasm. There are less than 30 documented cases in the world literature. We present a case which was diagnosed preoperatively using abdominal CT scan and angiography. The fact that the pedunculated tumor had undergone torsion with some necrosis precipitated symptoms of abdominal pain. This is the first reported case of this rare tumor presenting with torsion.
