Transverse colonic volvulus due to mesenteric fibromatosis: a case report

Background Colonic volvulus, a condition in which a colonic segment partially twists around its base, is the third leading cause of large bowel obstruction after colonic neoplasms and diverticular disease. However, volvulus of the transverse colon is the rarest type of large intestinal volvulus. Moreover, the occurrence of transverse colonic volvulus secondary to a benign tumor originating from outside the intestine has never been reported. We hereby report a case of transverse colonic volvulus caused by mesenteric fibromatosis. Case presentation A 53-year-old female with a history of rheumatoid arthritis and thyroid tumor presented with abdominal pain for 1 day. Abdominal computed tomography revealed intestinal torsion at the hepatic flexure. Twisted and obstructed mucosa of the transverse colon was observed during colonoscopy, but no tumor invasion of the mucosal surface was detected. A solid mass of a mesenteric origin with involvement of the transverse colon was observed during surgery. The mass was diagnosed surgically as transverse colonic volvulus induced by a mesenteric tumor. Hence, the patient underwent a right hemicolectomy. Histopathological results indicated mesenteric desmoid-type fibromatosis. The postoperative recovery was uneventful, and the patient was discharged 8 days after surgery. Conclusions Although mesenteric fibromatosis is rare, this disease should be considered when managing transverse colonic volvulus resulting from nonmucosal tumors.

Case report of an intra-abdominal desmoid tumour presenting with bowel perforation

Desmoid tumours are benign tumours originating from the musculo- aponeurotic structures of the body. They are mainly composed of collagen. These tumours commonly occur in post-partum women in whom they originate from the rectus abominus and in old surgical incisions. Here we present a case report of a young gentleman who presented with an acute surgical abdomen and subsequently underwent a laparotomy and was found to have an inflammatory mass. Histological analysis of this mass revealed mesenteric fibromatosis (desmoid tumour). I wish to present this interesting case because the patient was neither female nor someone who had previously undergone any surgery. It is rare for mesenteric fibromatosis to present with intestinal perforation and only one case been reported in the literature thus far (1). An important learning point from this case is that rare pathology can manifest itself with common signs and symptoms.

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

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.
