a Chest CT scan of a patient with symptomatic Mycobacterium intracellulare lung disease before initiation of treatment. The scan shows bronchiectasis, nodules, and reticular densities in the right middle lobe and lingular segment. Treatment started 4 weeks after checking this CT scan. b Chest CT scan at 6 months after the initiation of treatment showing substantial improvement. c Chest CT scan at 12 months after the completion of 18-month treatment for M. intracellulare lung disease. Radiographic lesions and symptoms worsened; bloody sputum was also noted. Four weeks after this CT scan was taken, M. abscessus subspecies abscessus, instead of M. intracellulare, was isolated. d Chest CT scan at 6 months after initial isolation of M. abscessus subspecies abscessus. The patient’s symptoms continued to worsen and sputum persistently tested positive for M. abscessus subspecies abscessus
