Figure 10.

Mycobacterium intracellulare infection (non-ILA) in a 72-year-old woman. (A, B) Axial CT images show linear opacity and ground-glass abnormality (arrowheads) in the subpleural area of the upper lung lobes. (C) Axial CT image at a lower level shows bronchiectasis and reticulation (straight arrows) in the middle lobe and lingula and centrilobular nodularity (curved arrows) in the left lower lobe. These findings are typical of nontuberculous mycobacterial pulmonary disease, suggesting that the abnormalities at the upper level are related to infection or postinfection change. The findings in this patient were not considered to indicate ILA.
