Right-sided intra-thoracic kidney associated to Bochdalek hernia in an adult patient

Diaphragmatic hernia of Bochdalek (BH) and intra-thoracic kidney (IK) are both rare congenital, developmental anomalies. In some extremly rare occasion, these two congenital anomalies can be associated in the same patient. The kidney typically exits the retroperitoneal space through the foramen of Bochdalek. The majority of IK and BH are discovered incidentally. A conservative approach can be proposed in asymptomatic cases. In this report, the case of a 35-year-old man presenting with 1-week of acute abdominal pain is presented. Chest radiography revealed a posterior mass in the right hemithorax, which was later confirmed by chest computed tomography and magnetic resonance imaging to be a congenital IK associated with a BH.
