Ball in the Wall: Mesenteric Fibromatosis-a Rare Case Report

Abhinav Deshpande et al. Indian J Surg Oncol. 2020 Sep.

Abstract

Introduction: Mesenteric fibromatosis-desmoid tumor of mesentery is a rare benign soft tissue tumor of mesentery. On CT, it mimics gastrointestinal stromal tumor (GIST).

Case report: A 44-year-old female with small intestinal mass, preoperatively diagnosed radiologically and pathologically as GIST.

Conclusion: Mesenteric fibromatosis is a rare tumor often mistaken for GIST. Histopathology and immunohistochemistry is the key as management of both the tumors differs.

Keywords: Desmoid tumor of mesentery; GIST; Mesenteric fibromatosis.
