Colitis on CT colonography

Case contributed by Dr Jeremy Jones

Presentation

Altered bowel habit and blood per rectum in a 52 year old female.

Modality: CT

.

Case Discussion

The presenting symptoms resulted in a referral from outpatient clinic for a CT pneumocolon.  No mass lesion was identified, but the study did demonstrate thickening of the ascending and transverse colon wall.

The colon wall should be extremely thin and almost inappreciable when the bowel is distended.  However, in the region of the hepatic flexure, there is definite thickening of the bowel wall. 

In is worth noting that this is an incidental finding and insufflation of the bowel in a patient with suspected colitis carries the risk of perforation.

Subsequent colonoscopy confirmed the diagnosis of Crohn's disease.
