[Radiographic findings of pulmonary nontuberculous mycobacteriosis other than Mycobacterium avium complex].
Almost all nontuberculous mycobacteria (NTM) cause opportunistic infection. Therefore, the radiographic findings of NTM have a tendency of nonspecific patterns modifying the predisposing conditions or diseases and we could not extract species specific radiographic characterizations in that situations. In this review, the NTM cases without predisposing conditions or diseases are submitted essentially. Mycobacterium kansasii cases show more or less the same patterns with TB cases. Mycobacterium fortuitum case shows nonspecific consolidations. Mycobacterium xenopi case shows solitary cavity in the upper lobe area. Mycobacterium gordonae case shows the same cavitary pattern. Mycobacterium abscessus case shows widely scattered tree-in-bud appearance foci. Weak virulence NTM like as Mycobacterium xenopi or Mycobacterium gordonae may form solitary cavity without predisposing conditions. The pattern of bronchial wall thickening seems to be one of the specific findings with NTM pulmonary infection.
