Another patient with non-tuberculous mycobacteria (NTM) lung disease due to Mycobacterium intracellulare who underwent right middle lobectomy and lingulectomy but 2 years later, developed recurrence with Mycobacterium chimaera. Pre-operative axial and sagittal CT images from 2010 showed right middle lobe (RML) and lingular bronchiectasis and atelectasis (arrows) due to M. intracellulare. Patient underwent surgical resection of both the RML and lingula in 2011. Post-operative images showed no abnormalities in the lung tissues previously occupied by the RML and lingula. In 2013, there was recurrence of NTM lung disease with M. chimaera, revealing consolidation in anterior right lower lobe (arrows in both axial and sagittal images), which now occupied the site of the previous RML.
