Abstract

The prevalence of lung diseases caused by nontuberculous mycobacteria (NTM) is increasing worldwide. Unlike pulmonary tuberculosis, endobronchial NTM diseases are very rare with the majority of cases reported in patients with human immunodeficiency virus infection and acquired immune deficiency syndrome. We reported a rare case of endobronchial Mycobacterium avium disease associated with lobar atelectasis in a young immunocompetent patient and reviewed the relevant iterature.

Figure

  Figure 1 Chest radiography reveals atelectasis of the right lower lobe.

• 

  Figure 2 (A) An axial chest computed tomography (CT) image at the level of the left atrium shows lobar consolidation of the right lower lobe. Note the fluid bronchograms in the dilated bronchi . (B) An axial chest CT image at the level of the right bronchus intermedius shows a hypertrophied and well-enhancing subcarinal lymph node (arrow). Note this lymph node attaches to the right main bronchus.

  Figure 3 A bronchoscopic image demonstrating an ulcerative endobronchial lesion on the medial side of the right main bronchus.

  Figure 4 Chest radiography reveals improvement of the atelectasis of the right lower lobe.
