Case Discussion
This case demonstrates a perineal hernia, also known as levator or pudendal hernia, a rare pelvic hernias, occurring through a defect in the pelvic floor musculature. Anterior hernias demonstrate herniation of the bowel through the urogenital diaphragm. Posterior perineal hernias are seen on CT as protrusion of loops of the sigmoid colon or rectum into the ischioanal fossa, as in this case.
