Presentation
Right iliac fossa pain and rebound tenderness.
Patient Data
Ascending colon shows proximal segment posterolateral diverticulum containing fecal matter with intact thick wall surrounded by pericolic fat stranding, thickened lateroconal fascia and mild colonic wall thickening. No signs of perforation or abscess formation.
Case Discussion
Features of acute uncomplicated diverticulitis involving the proximal part of ascending colon, with clinical presentation mimiking acute appendicitis. The patient would be treated conservatively.
Right-sided colonic diverticulitis is hard to suspect clinically as it is much less common than left-sided diverticulitis, occurs in younger age and mimics the most common differential acute appendicitis. It is hard to distinguish between both clinically and can be mistaken for carcinoma intraoperatively 1,2.
