Internal herniation of the abdominal wall

Clin Case Rep. 2019 Jan 29;7(3):575-576. doi: 10.1002/ccr3.2008. eCollection 2019 Mar.


A symptomatic arcuate line hernia should be considered in patients with acute lower abdominal complaints. This rare internal herniation is caused by a sharp ending of the posterior aponeurotic sheath of the rectus muscle, rather than the more common gradual delineation, and can cause strangulation or incarceration of abdominal contents.
