Background:
Lung disease due to aspiration is often unsuspected and represents a diagnostic challenge.
Case Report:
We report on a 23-year-old male patient with cough, fever and infiltrates on the chest radiograph. The lung biopsy showed granulomatous changes consistent with tuberculosis. The surgical lung biopsy revealed aspiration bronchiolitis with necrosis, granulomatous changes and particulate foreign material.
Results:
The aspirated matter could be identified only after repeated interrogation specifically directed to the matter. The patient had aspirated Lycopodium spores in the course of occasional fire-breathing.
Conclusions:
This is the first report on pulmonary disease due to aspiration of Lycopodium spores in the course of fire-breathing. It shows that the anamnesis is as crucial as histology for the definitive diagnosis of aspiration disease.

Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
