Hepatic mesenchymal hamartoma mimicking hemangioma on multiple-phase gadolinium-enhanced MRI.

Mesenchymal Hamartoma [MH] is a cystic benign liver mass occurring in children. Diagnostic confusion with hepatoblastoma may arise when alpha-feto-protein is elevated, and with hemangioendothelioma when imaging shows centripetal filling. We demonstrate one such case with progressive centripetal enhancement of a liver mass with Gadolinium enhanced multiple phase gradient-echo MRI, in a child with raised alpha-feto protein.
