This patient presented 45 days ago to the emergency department with severe right lower quadrant pain, the suspicion of acute appendicitis was high so he underwent an appendectomy and the appendix was surprisingly not inflamed.

He then presented with acute right lower quadrant abdominal pain and abdominal distention. Initial abdominal x-ray showed signs of intestinal obstruction. Complicated inflammation of the appendiceal stump was suspected.  The patient underwent this CT scan and an inflamed blind-ending tubular structure arising from the terminal ileum (rather than the cecum) was found suggestive of Meckel's diverticulitis.

The patient underwent surgery to relieve the obstruction and inflamed Meckel's diverticulum was found.
