Tree-in-bud pattern of chest CT images for diagnosis of Mycobacterium abscesses.

ABSTRACT:

Objectives

Changes of chest CT images in Mycobacterium and non-Mycobacterium abscesses in patients with lung disease were with a view to making an early diagnosis.

Methods

124 primary patients diagnosed with non-tuberculosis Mycobacterium infections with a positive sputum acid-fast smear were enrolled in this retrospective study. CT images and clinical data of these patients were analyzed.

Results

The 52 Mycobacterium abscess lung disease cases included bronchiectasis 82.7% (43/52), which was more easily detected bilaterally than unilaterally (29/52 vs. 14/52), lung consolidation 44.2% (23/52), nodules 44.2% (22/52), cavities 32.7% (17/52), tree-in-bud pattern 42.3% (22/52) and patchy shadow 63.5% (33/52) in CT images. Tree-in-bud pattern was more common in Mycobacter
