Etiology
Several etiological factors have been suggested for mesenteric IMTs, such as previous surgery or trauma, chronic infections and autoimmune diseases 2,3.
Clinical presentation
IMTs of mesentery often present with abdominal mass and the compressive effect of the tumor, such as pain and vomiting. They may also associated with a general inflammatory response like fever and weight loss.

CT
CT is the primary radiological modality for the diagnosis of mesenteric IMTs. On post-contrast CT images, IMTs usually show solid masses with ill- or well-defined margins and heterogeneous enhancement patterns that may suggest a malignant lesion 4.
