Leiomyomatosis peritonealis disseminata in a 50-year old woman: Imaging findings

Abstract

Leiomyomatosis peritonealis disseminata (LPD) - or diffuse abdominal leiomyomatosis - is a very rare benign abdominal entity. Only a little more than 100 cases have been reported in the English literature since its first description in 1965. Middle aged female are typically affected and the clinical presentation is rather aspecific. The differential diagnosis between benign LPD and diffuse peritoneal carcinomatosis or abdominal disseminated malignancy represents the crucial diagnostic challenge that can only definitively be made through biopsy and histologic analysis. Multimodal imaging features (ultrasound, CT, MR and PET) of a case of LPD diagnosed in a 50-year old female are presented with review the literature.
