Mesenteric Fat Necrosis Mimicking a Malignant Mesenteric Tumor: A Case Report

INTRODUCTION: Mesenteric fat necrosis, an uncommon benign condition, can present as a mass-forming lesion and can closely mimic malignant mesenteric disease on imaging. Because its radiologic findings may overlap with those of malignant mesenteric tumors, preoperative diagnosis can be challenging, particularly when tissue sampling is difficult. This report describes a rare case of mesenteric fat necrosis, presenting as an enlarging mesenteric mass suspicious for malignancy.
