A Tuberculous Bronchial Artery Aneurysm with Abnormal Findings on Autofluorescence Imaging Bronchoscopy

Pulmonary tuberculosis is a common disease that may result in hemoptysis. Fetal hemoptysis is known to be related to the rupture of a pulmonary aneurysm formed in the cavity wall. We herein report a case of non-cavity pulmonary tuberculosis that developed with massive hemoptysis following bronchial artery aneurysm. Bronchial artery embolization was performed, and autofluorescence imaging bronchoscopy was conducted one month after the anti-tuberculosis treatment. Bright-green color was observed in the ulcerative lesion with a white coat, corresponding to the bronchial artery aneurysm. This is the first report of the autofluorescence imaging observation of an ulcerative lesion caused by bronchial tuberculosis.
