Figure 3. Patient 6. Atypical mycobacterial infection in an asymptomatic 62-year-old woman with new radiographic abnormalities 16 months after right single-lung transplantation for emphysema. Transverse chest CT scan (10-mm collimation, lung window) shows severe emphysema in the native left lung and two small nodules in the left upper lobe (arrow). Resected thoracoscopic wedge specimen revealed granulomatous inflammation with numerous acid-fast bacilli. Cultures grew M avium-intracellulare complex.
