A rare case of partial diaphragmatic agenesis with thoracic liver herniation and anteriorly displaced intrathoracic kidney in an adult diagnosed by displaced diaphragmatic crus.

Diaphragmatic agenesis is a rare anomaly and usually occurs in the early neonatal period. Its exact pathogenesis from the embryologic viewpoint is still unknown. Its presentation in adulthood is extremely rare, with only 7 cases of hemidiaphragmatic agenesis reported in adults. They are usually associated with herniation of abdominal contents and are predominantly left sided. We present a case of right hemidiaphragmatic agenesis with anteriorly displaced crus and intrathoracic herniation of kidney, which is anterior and rotated along the horizontal plane, with herniation of liver and colon. The position of the crus was instrumental in making a diagnosis of diaphragmatic agenesis and for which the patient was operated upon and the defect was repaired.
