Vermiform appendix located within the cecal wall. Anomalies and bizarre locations.

The unusual finding of an acute appendix located within the posterior wall of the cecum, beneath the serosa, and its surgical removal is described. In order to remove the appendix, the cecal wall had to be incised. The appendix had no serosal covering, and had the gross appearance of a peeled seedless grape. The anatomy and embryology of the vermiform appendix, including this aberration, are presented briefly. A discussion of the difficult-to-find appendix is presented. The possibility exists that some of the reported cases of agenesis of the appendix could have been an overlooked intracecal appendix.
