On the basis of the imaging findings of numerous diverticula in the region of the sigmoid colon abnormality, this was considered to be a diverticular stricture. The other most predictive feature of malignancy, shouldered edges, was not convincingly seen. This case highlights the overlap in findings between diverticular and malignant strictures of the sigmoid colon, with the pathology analysis here showing that this was in fact a malignant stricture. 

Contrast this with this case in which the imaging was suggestive of a malignant stricture but post-operative pathology analysis identified a diverticular stricture.
