Bochdalek hernia is a congenital disease characterized by protrusion of the abdominal organs into the thorax through the posterior defect in the diaphragma. The detection of incidental bochdalek hernia has increased because of the widespread use of the multidedector computed tomography. It is very rare in adult population. Intrathoracic kidney in bochdalek hernia is uncommon. In this paper, a 78 year-old man who had bochdalek hernia with a kidney in the left side of the thoracic region is presented.
