We report a case of broncholithiasis secondary to pulmonary actinomycosis. Broncholithiasis has occasionally been reported in association with actinomycosis, but it is unclear if actinomycosis leads to lymph node calcification with subsequent erosion into the airway, producing a broncholith, or if an existing generic broncholith is secondarily colonized with Actinomyces. The patient had post-obstruction pneumonia, and computed tomography showed calcified nodules obstructing the bronchus intermedius and distal necrotizing pneumonia. The nodules included sulfur granules containing Gram-positive branching filamentous organisms consistent with Actinomyces. The finding of Actinomyces throughout the broncholith is strong evidence that the etiology of the broncholithiasis was a primary pulmonary Actinomyces infection.
我们报告了一例继发于肺放线菌病的支气管结石病。支气管结石病偶尔与放线菌病有关，但尚不清楚放线菌病是否导致淋巴结钙化，随后侵蚀气道形成支气管结石，还是已经存在的普通支气管结石继发被放线菌定植。该患者患有阻塞后肺炎，计算机断层扫描显示钙化结节阻塞中间支气管和远端坏死性肺炎。结节中含有革兰阳性分支丝状放线菌。整个支气管结石中均发现放线菌，这有力地证明了支气管结石病的病因是原发性肺部放线菌感染。
