Pedunculated liver hemangioma mimicking stomach neoplasm

Abstract

Hepatic hemangiomas are the most frequently seen benign liver mass. However, exophytic hepatichemangiomas, particularly pedunculated ones are very rare. They have various appearances that make thediagnosis difficult. We report a pedunculated hemangioma case which was misdiagnosed as gastrointestinalstromal tumor on computerized tomography scan. Magnetic resonance imaging revealed that the tumor was ahepatic hemangioma with a long peduncle originating from the right edge of the liver, extending into perigastricarea. Hepatic hemangioma with a long peduncle can be mistaken with other abdominal masses. Rememberingthis entity and knowing its imaging characteristics are the keys to diagnosis
