The diaphragm. Under surface. (Lumbocostal triangle not labeled, but costal and lumbar regions are visible.)

The Lumbocostal triangle or Bochdalek's foramen is a defect in the diaphragm normally posterior lateral. It is formed by the incomplete closure of the pericardioperitoneal canals by the pleuroperitoneal membrane.
This condition has also been associated with thoracic kidney, the presence of the kidney in the thorax instead of the usual abdominal position.
