CXR and CT of intrathoracic kidney
CXR AP (upper left) shows a rounded mass in the left lower lobe which appears posterior in location on the CXR lateral (upper right). Coronal and axial CT with contrast of the chest (below) shows the left kidney to be in the lower left hemithorax. In the operating room, a defect at the foramen of Bochdalek was noted and repaired after the kidney had been reduced into the abdomen.

The diagnosis was intrathoracic kidney due to congenital diaphragmatic hernia.
