We report a case of inflammatory myofibroblastic tumor (IMT) of the mesentery with no symptoms. A man in his 70s was found to have a mesenteric tumor by CT conducted to observe renal cysts at another hospital. The tumor had not been present on CT five months before. There were no abnormal laboratory data. Fluorine-18-fluorodeoxyglucose and positron emission tomography suggested malignancy. Partial resection of the small intestine was performed and the tumor was histopathologically diagnosed as IMT of the mesentery. IMT which develops in the abdomen usually occurs with local or systemic symptoms like abdominal pain, mass, or fever. We rarely find asymptomatic IMT of the mesentery. This case, fortunately, was diagnosed with no symptoms by periodic CT examination for another disease.
