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.

[edit] Clinical significance

The existence of this foramen might cause a congenital diaphragmatic hernia, Bochdalek hernia.

This condition has also been associated with thoracic kidney, the presence of the kidney in the thorax instead of the usual abdominal position.^[1]
