Abstract：Objective To explore clinical characteristics and causes of misdiagnosis of pulmonary actinomy-cosis ( PA) with endobronchial involvement. Methods The clinical data of one case of PA with endobronchial in-volvement was retrospectively analyzed. Results The patient presented to our department with a low density in the lower lobe medial basal segment for half a month. Chest CT showed a low density shadow accompanied with obstruc-tive pneumonia in the lower lobe medial basal segment, which was supposed to be a mucous plug or a tumor. Multi-disciplinary discussions considered the possibility of endobronchial low-grade malignancy. The biopsy was performed on the bronchoscope, and the pathologic diagnosis was PA with endobronchial involvement. The symptoms were im-proved significantly two weeks after the patient was given oral administration of Moxifloxacin (0. 4 g/d). CT showed evident lesion absorption. Conclusion PA with endobronchial involvement is a rare disease in clinical settings. If the imaging findings indicate persistent space-occupying lesions in the lung or the trachea, early pathological exami-nation should be performed to reduce misdiagnosis.
