Nontuberculous Mycobacterial Pulmonary Infection in Immunocompetent Patients: Comparison of Thin-Section CT and Histopathologic Findings

Abstract

Regardless of the specific infective mycobacterial species, the most common thin-section CT findings of NTM pulmonary infection are bilateral small nodules, cylindric bronchiectasis, and branching centrilobular nodules. These findings correspond histopathologically to bronchiolectasis and bronchiolar and peribronchiolar inflammation with or without granuloma formation.
