Structure/Morphology
The ileocecal fold is a fold of peritoneum that extends from the anteroinferior surface of the terminal ileum to the anterior aspect of the mesoappendix, although it may attach to the appendix directly or the cecum (Standring, 2016).
Key Features/Anatomical Relations
The ileocecal fold forms the anterior boundary of the inferior ileocecal recess. This recess is well developed in the young, but is usually obliterated by fat in adults (Standring, 2016).
