Bochdalek hernia is a congenital diaphragmatic defect that allows abdominal viscera to herniate into the thorax. Intrathoracic kidney is a very rare finding representing less than 5% of all renal ectopias. In majority of individuals, the thoracic kidney is benign and asymptomatic. It is most often detected incidentally on chest imaging or at the time of thoracotomy for a suspected mediastinal tumor.
