title: [A case of exohepatic pedunculated hepatocellular carcinoma suspected of adrenal tumor].
abstract: A case of exohepatic pedunculated hepatocellular carcinoma that was clinically diagnosed as nonfunctioning adrenal tumor is reported. A 66-year-old man was admitted to our hospital for further examination of unstable angina pectoris. Abdominal echogram and CT scan revealed a large tumor in the right retroperitoneal space. Selective right renal arteriography demonstrated that the tumor was fed by the capsular branch of right renal artery and the right adrenal artery. Adrenal function was normal. Preoperative diagnosis of right nonfunctioning adrenal tumor was made. On operation we found that the tumor was pedunculated from the liver and adhered massively to both right kidney and vena cava. The tumor and right kidney were removed. A histopathological examination demonstrated well differentiated hepatocellular carcinoma (Edmondson's grade II type).
