Over the last 30 years it has become increasingly clear that nontuberculous mycobacterial (NTM) lung infections and bronchiectasis are closely related disorders. Although incontrovertible proof is lacking, there is a growing consensus of opinion that NTM lung disease characterized by nodules and bronchiectasis (nodular/bronchiectatic NTM lung disease) may be a consequence of preexisting bronchiectasis that predisposes to NTM infection and disease. To use published diagnostic guidelines effectively, physicians must become familiar with the disease-causing potential of individual NTM species. Essentially all NTM patients have bronchiectasis, so optimal overall patient management requires successful therapeutic strategies for both NTM infection and bronchiectasis.
