Internal hernia is a rare cause of small bowel loop obstruction. Hernia through a defect of the broad ligament is extremely rare. A female patient who had received laparoscopic oocyte retrieval 20 years ago suffered from intermittent lower abdominal cramping pain and vomiting. Internal hernia through the defect of the broad ligament is confirmed through a series of imaging studies and surgical exploration. To the best of our knowledge, this is the first case of internal hernia through a defect of the broad ligament in which the small bowel loop inside the herniated sac is collapsed rather than dilated, as noted on the computed tomography and surgical finding.
