Hepatic hemangioma in the presence of fatty infiltration: an atypical sonographic appearance.

The typical hepatic cavernous hemangioma presents no diagnostic difficulty at sonography. In contrast, an atypical hemangioma may cause great concern and result in costly and time-consuming investigations. The presence of diffuse fatty infiltration may result in an atypical echo-poor appearance of the hemangioma. Under such circumstances, computed tomography (CT) may not allow definitive diagnosis and magnetic resonance imaging (MRI) may be necessary.
