Atypical Hepatic Hemangioma With Progressive Centrifugal Enhancement Pattern Mimicking Malignant Liver Lesion.

Hepatic hemangioma is a common benign vascular hepatic lesion with typical imaging features. However, hepatic hemangiomas with atypical radiological characteristics can sometimes be diagnostically challenging. Here, we report a case of an elderly patient with colonic adenocarcinoma who was incidentally found to have an atypical hepatic hemangioma showing a progressive centrifugal enhancement pattern instead of a typical centripetal pattern on contrast-enhanced computed tomography mimicking a malignant liver lesion.
