A missing kidney and a hidden congenital diaphragmatic hernia.

Congenital intrathoracic kidney (ITK) is a rare condition, which is usually discovered incidentally in asymptomatic children who do not need any intervention. However, it may be associated with congenital diaphragmatic hernia (CDH), in which case it requires urgent surgical intervention. We present a case of prenatally diagnosed ITK associated with a left CDH that was operated on day 5 of life. The neonate is currently well at 15 months of age.
