Isolated caecal necrosis-a case study.

A patient with right iliac fossa pain underwent CT angiography which demonstrated isolated caecal necrosis with associated superior mesenteric artery (SMA) stenosis. This was supported by colonoscopic findings and histopathological analysis. Isolated caecal necrosis is a rare presentation of ischaemic colitis.. Clinical and imaging findings of ischaemic colitis may mimic other pathologies. To improve diagnostic accuracy both referrers and radiologists should be aware of risk factors associated with ischaemic colitis. Isolated bowel wall thickening and pneumatosis of a colonic segment on CT are suggestive of focal bowel ischaemia, in the right clinical context.
