Click 39-Year old male with Acute Mesenteric Ischaemia. Axial nonnenhanced abdominal CT scans demonstrating increased density of the small bowel wall (and lumen) correlated with histopathology slide confirming the presence of haemorrhage in the bowel wall (and lumen). Also seen is haemorrhage in thickened muscularis propria, low density submucosal layer and dense vein consistent with recent thrombosis. GE Lightspeed 4 slice CT scanner;5mm slice thickness.

Click Case 2 was found to have haemorrhagic/ ischaemic bowel loops and venous thrombosis at surgery. Unenhanced abdominal CT scan demonstrating dense bowel loops in left mid-abdomen (GE Lightspeed 4 slice CT scanner;5mm slice thickness).

Click Case 3 demonstrating arterial occlusion and ischaemic bowel loops on the Rt side of the abdomen at surgery. Enhanced abdominal CT scan demonstrating an occluded major branch (Rt) of the superior mesenteric artery (arrow head) with no enhancement of the wall of the Rt sided bowel loops (open arrow) compared with enhancing Lt sided loops (closed arrow). (GE Lightspeed 4 slice CT scanner;5mm slice thickness, omnipaque (iohexol) 300mg/ml 100mls @ 2ml/s).

Click Case 4 was found to have incomplete occlusion of the mesenteric artery (enhanced CT) with evidence of ventricular thrombus and splenic infarcts. Bowel wall enhancement could be identified throughout. The patient recovered spontaneously (on anticoagulants) and did not require surgery.
