Summary

This report describes a rare case of mesenteric lipoma revealed by chronic abdominal pain in 22-year-old Tunisian man.
Diagnosis is challenging because of nonspecific clinical presentation and in the absence of risk factor. The CT scan images were most consistent with a lipoma and shows no signs of malignancy. Complete excision of the lesion was performed with a clear plan of cleavage between the tumour and the ileal mesentery.
Histopathologic examination showed benign lipoma. The postoperative period was uneventful and no recurrence has been diagnosed.
