摘要
Endobronchial actinomycosis is a rare manifestation of thoracic actinomycotic infection that can mimic malignancy, tuberculosis, fungal infection or lung abscess, and thus usually leads to a misdiagnosis. Here, we reported an unusual case of actinomycosis with endobronchial involvement that was initially misdiagnosed as a lung abscess with organizing pneumonia. Endobronchial actinomycosis was confirmed by bronchial pathology, and the patient was treated successfully with a 6-month course of antibiotics, showing both marked symptomatic and image improvement. The follow-up bronchoscopic image revealed nearly total resolution of the endobronchial nodule and no evidence of obscure abnormalities. This case highlights the critical role of bronchoscopy, rather than conventional chest computed tomography only, in the definite diagnosis of endobronchial actinomycosis. Repeated bronchoscopy following treatment is mandatory, given the close association of endobronchial actinomycosis with a broncholith, inhaled foreign body and lung cancer.
