Lateral fossa

Last revised by Vincent Tatco on 2 Aug 2021

The lateral fossae are concave depressions of peritoneum in the paravesical space that lie between the lateral umbilical folds and the lateral parietal peritoneum. The lateral fossae are the smallest of the anterior paravesical fossae, and typically partially contain the cecum and/or sigmoid colon. The deep inguinal ring lies lateral to the inferior epigastric vessels at the anteromedial aspect of the fossa, and is the origin of indirect inguinal hernias.
