Nontuberculous Mycobacterial Pulmonary Disease: A Clinical and Radiologic Update

Nontuberculous mycobacterial pulmonary disease (NTM-PD) is increasingly recognized in the U.S. and worldwide as a debilitating disease that is challenging to diagnose and manage. Beyond the principle task of recognizing the protean imaging manifestations of NTM-PD, radiologists will need to appropriately communicate with pulmonology and infectious disease colleagues in multidisciplinary management discussions. This update on nontuberculous mycobacteria (NTM) species, their clinical significance, and imaging features aims to support these roles. Terminology mirrors that laid out by the American Thoracic Society (ATS) and Infectious Disease Society of America (IDSA) published guidelines on NTM-PD. 1
