Pedunculated Hepatic Hemangioma Masquerading as a Peritoneal Tumor. A Case Report

Mostafa El Hajjam et al. Pol J Radiol. .

Abstract

Background: Although being classically located inside the liver parenchyma, hemangiomas may occasionally develop outside the extra-hepatic capsule, thus appearing as a pedunculated mass.

Case report: We report the case of a 66-year-old anal cancer female patient presenting with an asymptomatic sub-hepatic mass. Incidental diagnosis of a pedunculated hepatic hemangioma was strongly suggested by the typical imaging features on computed tomography (CT) and magnetic resonance (MR) examinations, and was confirmed by histopathological examination.

Conclusions: Exophytic pedunculated growth is a rare and atypical feature of hepatic hemangioma. Thin contrast- enhanced sections and multiplanar CT and MR scan reformations helped to the final diagnosis of hemangioma, showing its origin from the liver edge. Surgical resection is mandatory to prevent threatening mass pedicle torsion.

Keywords: Hemangioma, Cavernous, Central Nervous System; Liver Neoplasms; Magnetic Resonance Imaging.
