The clinical history was one with a strong suspicion for ischemic bowel.  Atrial fibrillation and a prior vascular event (stroke), along with a steeply elevated lactate.

The SMA thrombosis is fairly proximal and totally occludes the lumen with end organ consequences.

The small bowel is almost devoid of enhancement.   The other features of ischemic gut, such as intra-mural gas and portal venous gas, are not yet evident.

Take a look at the D3-D4 junction to see the normal bowel wall enhancement vis-a-vis the remaining of the small bowel to be convinced of the absence of enhancement elsewhere.

This patient died on the day of the scan.
