Case Discussion

This case demonstrates a classical appearance of an inflamed diverticulum in the sigmoid colon. The case was managed as a non-complicated diverticulitis with conservative treatment at home.  

In some cases, it can be difficult to distinguish diverticulitis from colon cancer, especially when there is prominent focal colonic thickness and the inflamed diverticulum may not easily be spotted.
