Intestinal obstruction is a very common cause for presentation to the Emergency Department while internal hernia is a rare cause of obstruction. Among internal hernias, defects of the broad ligament (BL) are extremely rare. Defects of the BL can be either congenital or secondary to surgery, pelvic inflammatory disease, and delivery trauma. Herein, we report a 43-year-old lady, who presented with signs and symptoms of perforated small bowel for which a diagnosis of acute peritonitis was made. At laparotomy, the cause of the perforation was found to be an internal hernia through a defect in the right BL. Surgical management was taken with a smooth postoperative course.
