The complex embryogenesis of the kidney may lead to several renal anomalies, renal ectopia included. Of all kidney ectopias, the intrathoracic one is the least common. Congenital diaphragmatic hernia is usually seen in the neonatal period, mainly because of failure to close the posterolateral diaphragm. Intrathoracic renal ectopia due to congenital diaphragmatic hernia has a reported incidence of 0.25% [1]. The association of a duplex kidney collection system and an intrathoracic renal ectopia is extremely rare. So far, only one infant patient case has been reported [2]. Herein, we report on an adult case of intrathoracic renal ectopia with a double kidney collection system associated with an Ipsilateral congenital diaphragmatic hernia.
