Co-existence of organising pneumonia in a patient with Mycobacterium Avium Intracellulare pulmonary infection

Abstract

Non-tuberculous mycobacterias (NTMs) have many clinical manifestations in humans, depending on the underlying immunological status. We present a patient with Mycobacterium avium intracellulare pulmonary infection and co-existing, biopsy proven non-granulomatous organising pneumonia in distinct regions within the lungs. Treatment consisting of anti-mycobacterial therapy and corticosteroids led to clinico-radiological resolution. This case represents a potential broader clinico-pathological manifestation of Mycobacterium avium intracellulare.
