Recently, a news story titled ‘Woman’s Four-Month Cough Caused by a Tooth’ has drawn widespread attention. According to reports, the woman suffered from a persistent dry cough for over four months. Despite visiting multiple hospitals and trying various cough medications and tests, no cause was identified—until a chest CT scan unexpectedly revealed a high-density foreign object in her right lung. Upon removal via bronchoscopy, the object turned out to be a human tooth. Experts believe the tooth was likely inhaled into her airway during childhood, where it remained lodged for years, causing chronic irritation and inflammation that led to the persistent cough. Although such cases are extremely rare, they highlight an important diagnostic consideration: unexplained chronic cough—especially in individuals with a history of choking in childhood—may stem from an airway foreign body. Timely imaging and specialist evaluation can help prevent misdiagnosis and delayed treatment. This case also underscores the importance of multidisciplinary collaboration in diagnosing complex medical conditions.
近日，一则‘女子咳嗽4个多月，元凶竟是一颗牙齿’的新闻引发广泛关注。据报道，该女子持续干咳超过四个月，辗转多家医院，尝试了多种止咳药物和检查，始终未找到病因。最终，在一次胸部CT检查中，医生意外发现其右肺内有一高密度异物，经支气管镜取出后，竟是一颗人类牙齿。专家分析，这很可能是患者在幼年时期因意外将牙齿吸入气道，长期滞留肺部，引发慢性刺激和炎症，从而导致顽固性咳嗽。此类病例极为罕见，但提醒我们，长期不明原因的咳嗽，尤其是儿童期有呛咳史的患者，应考虑气道异物的可能性。及时进行影像学检查和专业评估，有助于避免误诊和延误治疗。这一案例也凸显了多学科协作在复杂疾病诊断中的重要性。
