An unusual case of congenital mesocolic hernia.

An internal hernia is defined as the herniation of viscera through an anatomic or pathologic opening within the confines of the peritoneal cavity. This herniation may be persistent or intermittent. Because of the risk of strangulation of the hernia contents, even small internal hernias are dangerous and may be lethal. Preoperative misdiagnosis has been reported to be elevated.
