一位68岁的妇女向急诊科提出了3天的呼吸急促、喘息、干咳、发烧和发冷的病史。当她呼吸周围空气时,她的血氧饱和度是96%。在左下叶肺检查发现裂纹。的胸部电脑断层扫描显示阻塞支气管石在左下叶支气管(在面板,箭骨窗)与支气管周围的地面玻璃和斑片状实变(图B,肺窗设置)。纤维支气管镜检查发现一个松散的支气管石,阻碍左下叶支气管近端(图C)。的支气管石,测量了1乘1.45厘米(图D),轻轻地缩回了。弯曲是最

患者女性,68岁,因出现呼吸急促、喘息、干咳、发烧和发冷3天而就诊于急诊。

检查发现,患者正常呼吸时,血氧饱和度是96%。患者左下叶肺听诊出现爆裂声。胸部CT扫描显示,左下叶支气管出现阻塞性支气管石(图A箭头),周围出现毛玻璃样和斑片状实变(图B)。支气管镜检查发现,一个松散的支气管石阻塞在左下叶支气管近端(图C)。使用支气管镜轻轻取出支气管石,大小约为1*1.45厘米(图D)。



支气管石最常是由于支气管周围淋巴结钙化并迁移到支气管管腔形成。慢性肉芽肿性感染(如组织胞浆菌病或肺结核)后可引起淋巴结钙化。对患者的支气管肺泡灌洗液培养,显示结核分枝杆菌、细菌和真菌阴性。使用γ干扰素释放试验来检测患者既往结核杆菌暴露,结果显示阴性,血清学检测显示组织胞浆菌阴性。

患者最后接受抗生素治疗其阻塞性肺炎,经治疗其症状消失。
