A patient presented with an acute episode of bright red blood in her stool. The incidental liver mass seen in segment 4 was suspected to represent a cholangiocarcinoma due to associated mild intrahepatic biliary ductal dilatation and suspicion for capsular retraction. Pathology confirmed that this lesion represented a sclerosing hemangioma. This case report corroborates prior observations that degenerative changes in hemangiomas-sclerosis, narrowing of vascular channels, thrombosis, infarct, hemorrhage-may produce atypical radiographic findings. Since these atypical radiographic features may suggest a primary or metastatic malignancy, the protean appearance of hemangiomas remains an important consideration in the evaluation of hepatic masses.
