Congenital-type internal hernias have the potential to cause small bowel obstruction well into adulthood. Congenital-type internal hernias include left paraduodenal, right paraduodenal, foramen of Winslow, pericecal, sigmoid mesocolon, transomental, small bowel mesentery, and broad ligament hernias. This review summarizes CT imaging features and complications of congenital internal hernias using a systematic approach based on abdominopelvic quadrants and key anatomic features. CT imaging will continue to be commonly used to evaluate abdominal pain. Anatomical landmarks and characteristic CT findings can help identify congenital internal hernias as a potential cause of abdominal pain.
