Nodular bronchiectatic mycobacterium avium complex pulmonary disease

Nodular bronchiectatic mycobacterium avium complex pulmonary disease is a morphological from of pulmonary mycobacterium avium complex infection although it is worthwhile understanding that there can be spectrum of the disease with mixed forms. 

This form may have greater predilection in postmenopausal women.

Although non specific may have a tendency towards the right middle lobe and lingular division of the left upper lobe 2.

In the nodular form, lung parenchymal abnormalities have been shown to demonstrate significant decrease in extent on imaging following antibiotic treatment (usually macrolide containing regimens) and with this improvement being mainly related to the improvement of cellular bronchiolitis.
