Abstract:
A 42 year old female was admitted to our hospital due to abnormal shadow on her chest X-ray. She had no symptoms. Chest X-ray and computed tomography (CT) scan revealed solitary nodule on left S10. Bronchofiberscopy was perfomed, but it could not establish pathological diagnosis. Thoracoscopic surgery was performed. It revealed that solitary nodule was Mycobacterium avium infection. Majority cases of Mycobacterium avium infection showed multiple nodules or infiltration shadows on bilateral lungs. But in our case, CT scan showed a solitary nodule, causing differential diagnosis from lung cancer to be difficult.

Pulmonary Tuberculosis I
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.

Here is a detailed explanation of its pathophysiology:
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...
