Liver teratoma

True liver teratomas are exceptional tumors, with only 25 cases reported in the radiology literature. Most cases reported were either intraperitoneal or retroperitoneal teratomas that had invad- ed the liver. The authors present a 27-year-old woman with a liver complex mass found incidentally at computed tomography (CT). The different imaging studies demonstrated that the lesion was composed of macroscopic fat, with a central soft tissue component and a calcification. The patient underwent surgery and the final diagnosis was a benign liver teratoma. (Acta gastroenterol. belg., 2008, 71, 275-279).
