Rib fractures are common injuries seen in the emergency department, and occur most of-ten following blunt thoracic trauma. However, violent or sustained coughing can also cause complications such as pneumothorax and rib fracture. We report a 50-year-old man who pre-sented to the emergency department with an intermittent nonproductive cough for 8 days and sudden onset of right side chest pain after an episode of violent paroxysmal coughing. The initial chest radiograph did not reveal a rib fracture. Subsequent chest computed tomography demonstrated a linear nondisplaced fracture at the lateral aspect of the right 8th rib. The pa-tient gradually improved after medical treatment and was discharged the next day.
