Sigmoid stricture: an unusual presentation of perforated appendicitis with abscess formation.

Appendicitis is the most common acute surgical condition affecting the abdomen. The manner of onset and location of pain depend, to a great extent, upon the different anatomical positions of the appendix and its proximity to the parietal peritoneum which senses the location of the inflammatory process. When perforation occurs, abscess formation or diffuse peritonitis may develop. We wish to report an unusually rare case of perforated appendicitis with abscess formation presenting clinically and radiologically as a sigmoid stricture.
