We report a case of late presentation of traumatic rupture of the diaphragm discovered incidentally on chest radiography (CXR) during an annual medical checkup. A 60-year-old man suffered severe blunt trauma from heavy steel frames collapsing against his back, resulting in pelvic and femoral fractures as well as pulmonary contusions. The patient recovered, but 10 months later CXR performed for lung cancer surveillance during an annual medical checkup revealed a traumatic rupture of the diaphragm. Video-assisted thoracic surgery was performed with reduction of the intestine and primary closure of the diaphragmatic defect. The patient recovered uneventfully. This report serves as a useful reminder that a medical history of severe blunt trauma should provoke a high index of suspicion for diaphragmatic rupture during annual medical surveillance.
