Pedunculated Intraperitoneal Lipoma Presenting as Ovarian Torsion: A Case Report

Abstract

A lipoma is a very common (prevalence 39%) benign soft tissue tumour that is composed of mature fat. Lipomas, though common on external surface of body, also have been reported in mediastinum, chest wall, thorax, retroperitoneal areas and pelvis. In Gastrointestinal Tract (GIT), lipomas are mainly found in the submucosa and subserosa of the small and large intestine. An eightyear-old female child presented with a feature suggesting torsion of the dermoid ovarian cyst. The clinical features included sudden abdominal pain, vomiting and other symptoms suggesting a differential diagnosis of appendicitis or an ovarian cause. Serum markers for carcinoma were normal. The Contrast Enhanced Computed Tomography (CECT) showed a right iliac fossa fat density with few internal septations and Magnetic Resonance Imaging (MRI) confirmed the torsion of the pedunculated mass and histopathological examination showed the mass as lipoma. The site of the lipoma, presented in this case, is rare. Though the presentation of intraperitoneal lipoma is rare, this should be considered as differentials in young patients presenting with features of ovarian torsion. The presentation of intraperitoneal lipoma especially in young patient is rare which is mostly an incidental finding in a laparotomy and mostly present as a case of obstruction or abdominal pain.
