Clinical Presentation and Intervention: A 45-year-old man was admitted with a painful abdominal mass. Abdominal computed tomography demonstrated a well- demarcated tumor in his left hemiabdomen, with a large fat component and areas of soft tissue attenuation suggestive of liposarcoma. Intraoperative findings showed a tumor arising from the greater omentum. The tumor was completely removed, and histopathology confirmed a pseudotumorous type of sclerosing mesenteritis with dominant mesenteric lipodystrophy. Conclusion: This case showed that a pseudotumorous type of sclerosing mesenteritis should be considered in the differential diagnosis of the mesenteric tumors. © 2015 S.
