Abstract

Intrahepatic cholangiocarcinoma (ICC) classically presents as irregular soft tissue lesions. Very rarely, ICC may manifest as a predominantly cystic mass. Here, we describe a 59-year-old man who was referred to the hospital due to abdominal pain. The presentation was highly suggestive of a hepatic cyst based on MRI. 18F-FDG PET/CT could not exclude a malignant hepatic tumor due to the high metabolism in the margin. Subsequently, the patient underwent a left hemihepatectomy. Histopathology revealed malignant ICC.
