Abstract

Mycobacterium massiliense is newly identified rapid-growing nontuberculous mycobacterium, but there are no reports of this mycobacterium species being the cause of human illness. We describe one case of Mycobacterium massiliense infection presenting as antibiotic-resistant acute pneumonia that resulted in surgical treatment.

  Figure 1 (A) Chest radiograph on admission. Multiple aggregated nodules and a consolidative lesion were noted on the right and left upper lobes, respectively. (B) Chest radiograph 25 days after admission (before surgical resection). The consolidative lesion on the left upper lobe had become aggravated. (C) Chest CT scan 79 days before admission. A small cavitary nodule was noted on the left upper lobe. (D) Chest CT scan 9 days after admission. A rapidly progressive consolidative lesion was noted on the left upper lobe.
