Congenital diaphragmatic hernia with intrathoracic kidney: case report, review of the literature, and strategy for treatment in neonates and infants.

Background: Congenital diaphragmatic hernia (CDH) is a rare developmental defect in the diaphragm, occurring in 2 in 10,000 births. Herniation of intraperitoneal organs through the diaphragmatic opening is always present, however few cases mention the herniation of retroperitoneal organs, such as a kidney. Due to the rarity of this condition, the optimal treatment strategy remains unclear.
