1. To provide an overview of the diverse etiologies frequently associated with mesenteric venous thrombosis (MVT) in order to work out the typical population at risk, since MVT is nowadays often incidentally detected on MDCT 2. To illustrate MDCT features of associated venous bowel ischemia depending on the underlying  pathology

1. The most frequent underlying pathologies associated with MVT are: Tumors (pancreas, liver) Inflammatory conditions (pancreatitis, colonic diverticulitis) Hematologic disorders Liver cirrhosis Recent operations Miscellaneous causes Unknown etiologies  2. MDCT features of venous bowel ischemia most often occur with hematological disorders 3. MVT, complete or partial, consists either of blood clots or tumoral tissue, the latter namely in pancreatic adenocarcinoma.

1. MDCT features of MVT are seen with a great variety of underlying diseases; some of them may never be disclosed. 2. The radiologists should be aware of the typical patient at risk so that suspicion can be raised early in the appropriate context. 3. Signs of venous bowel ischemia are infrequently associated with MVT, mostly occurring in coagulopathies or hematologic disorders, reflecting the underlying systemic involvement.
