Internal herniation of the abdominal wall

Abstract

Key Clinical Message 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.
