肋骨骨折是在急診室常見的損傷，其中最常發生鈍性胸外傷，但劇烈或持續咳嗽 也能相關的一些併發症，如氣胸和肋骨骨折。我們報告一個50 歲的男子間歇性的咳嗽 8 天，劇烈的陣發性咳嗽發作後右胸痛突然發作。胸部X 光顯示無異常。其後的胸部 電腦斷層發現右第八肋骨側面線性非位移性骨折。如病人表現為長期或嚴重的咳嗽， 一但突然胸痛發作時應懷疑咳嗽引起的肋骨骨折。病患接受內科治療改善後隔天就平 安出院。

Rib fractures are common injuries seen in the emergency department, and occur most often 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 presented 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 patient gradually improved after medical treatment and was discharged the next day.
