Superior mesenteric vein thrombosis

Case contributed by Dr Matt Dentry


Severe left sided abdominal pain with guarding. Raised WCC.

Patient Data

Age: 45 years
Gender: Male

A long, contiguous segment of distal small bowel (within the LLQ) is markedly concentrically thick walled but still demonstrates mucosal enhancement. Mesenteric fat stranding and free fluid. 

Superior mesenteric vein is not opacified inferiorly and more superiorly low attenuation is seen centrally within the lumen, which is expanded. No extension into the portal vein. 

Case Discussion

Superior mesenteric vein thrombosis can result in venous congestion and eventually bowel infarction.
