Hyperdynamic hemangioma with proximal arterioportal shunting: a rare manifestation

Arterioportal shunting, when associated with hemangioma, is usually small, peripherally located, and without hemodynamic significance. Proximal arterioportal shunting occurring in hemangioma has rarely been reported. Herein we report a patient with renal cell carcinoma who simultaneously was found to have a hyperdynamic hemangioma in the liver. The imaging features were confusing and evoked diagnostic difficulty before operation. (orig.)
