Case contributed by Dr Tommaso Buzzegoli

Presentation

70 year old man hospitalized after a spontaneous deep vein thrombosis. Laboratory showed leukocytosis and elevation of CRP, a screening abdominal CT was performed.

Patient Data

Age: 70
Gender: Male

Triphasic liver scan was performed which demonstrates a protruding mass in IV and V segment of the liver with a possible infiltration of the gallbladder. In arterial and portal venous phase the lesion mimics a cavernous hemangioma. Ring enhancement is showed during delayed phase consistent with hepatocellular carcinoma. The liver otherwise is unremarkable. No features of cirrhosis or portal hypertension are noted.

Case Discussion

Histological diagnosis of hepatocellular carcinoma (HCC) was confirmed. This is an unusual case of HCC that mimics a cavernous hemangioma. The most important image feature which help to make the correct diagnosis is the the rim enhancement persistent in delayed phase.
