Fig. 1B. Pulmonary Mycobacterium abscessus infection in 64-year-old
woman. Axial thin-section CT scan (2.5-mm collimation, 70 mA, 120 kVp)
obtained at level of main bronchi shows nodules (arrow) smaller than
10 mm in diameter in both lungs.

Fig. 1C. Pulmonary Mycobacterium abscessus infection in 64-year-old
woman. CT scan obtained at level of distal bronchus intermedius shows small
centrilobular nodules (arrow) with tree-in-bud appearance suggesting
bronchiolitis and multiple nodules smaller than 10 mm in diameter.

Fig. 2A. Pulmonary Mycobacterium abscessus infection in 37-year-old
woman. Posteroanterior chest radiograph shows large cavity in right upper lung
zone surrounded by air-space consolidation inferiorly and apical pleural
thickening superiorly. Also note reticulonodular opacities in left upper lung
zone and volume loss in upper zones of both lungs.

Fig. 3B. Pulmonary Mycobacterium abscessus infection in 44-year-old
woman. Follow-up radiograph obtained 1 month after specific antibiotic
treatment with amikacin, cefoxitin, and clarithromycin shows lung lesions are
nearly completely resolved.
