Abstract
We report a case of a 58-year-old woman who was diagnosed as having sarcoidosis 2 years previously. She was referred to our hospital because of a liver tumor. An abdominal contrast computed tomography scan showed a ring-enhanced tumor, 14 cm in diameter, in the right lobe of the liver and swollen lymph nodes in the hepatoduodenal ligament and paraaortic lesion. 18-fluorodeoxyglucose-positron emission tomography (FDG-PET) showed abnormal FDG uptake at the lymph node in the hepatoduodenal ligament, but the uptake at the paraaortic lymph node was obscure. We performed right hepatectomy and lymph node dissection, and the pathological diagnosis of the liver tumor was intrahepatic cholangiocarcinoma. No metastasis was detected in the dissected lymph nodes, and all lesions were diagnosed as sarcoid nodules consisting of epithelioid cells without caseous necrosis.
