Abstract: Knowledge of development and various possible positions of the appendix is important in understanding the pathophysiology of appendicitis. In the present case, we report on a lateral pouch type of appendix in a formalin-embalmed male cadaver. The appendix was found to be situated in a space between the caecum and the lateral abdominal wall. A short band of peritoneum extended from the right iliac fossa to the base of the appendix. The terminal part of the ileum was retroperitoneal and it was vertically situated in the right iliac fossa. Both the ileocaecal junction and the base of the appendix were located at the posterolateral wall of the caecum. The mesoappendix was unusual in position, and it extended from the appendix to the anterolateral wall of the caecum and commencement of the ascending colon. Documentation of rare anatomical variants of the appendix may hold significant clinical importance in diagnosis as well as surgical treatment of appendicitis.
