Resolving The Diagnostic and Management Dilemma: A Case of Giant Sporadic Mesenteric Fibromatosis And Review Of The Literature

Mesenteric fibromatosis (MF) is a benign intra-abdominal mesenchymal tumour and its radi-ological features are nonspecific leading to frequent misdiagnosis and current literature for man-agement consensus is lacking. We describe a case and review the literature. A 26-year-old gentleman presented with symptomatic abdominal distension and an epigastric mass to our institution. Imaging showed a large heterogenous mass arising from the root of the mesen-tery. En bloc resection including right hemicolectomy and small bowel resection was performed for proper tumour clearance. Histology revealed mesenteric fibromatosis with clear margins. The patient has been disease free for 18 months. Sporadic giant MF is a rare clinical entity that presents as both a difficult diagnostic and man-agement issue. Despite the use of imaging and pre-operative biopsy to improve diagnostic rates, treatment is complex and may result in radical resections associated with significant morbidity. Surgery with disease-free resection margins provides the best possibility of cure with no recur-rence in patients who are symptomatic or have complicated disease that are deemed resectable
