We report a case of mesenteric inflammatory myofibroblastic tumor (IMT). A 78-year-old man was found in computed tomography to have a mesenteric mass. The tumor was identified by fluorine-18-fluorodeoxyglucose and positron emission tomography (FDG-PET) as potentially malignant, necessitating jejunostomy. The solid surgical tumor specimen was determined histopathologically to be an IMT. FDG-PET is thus useful for diagnosing IMT. We review the Japanese literature on mesenteric IMT and FDG-PET findings in such cases.
