title: Sclerosing Mesenteritis Presenting as a Pseudotumor of the Greater Omentum.
abstract: OBJECTIVE
  The aim was to demonstrate a diagnostic challenge of sclerosing mesenteritis initially considered as liposarcoma.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  This case showed that a pseudotumorous type of sclerosing mesenteritis should be considered in the differential diagnosis of the mesenteric tumors.
