Abstract:
Pulmonary tuberculosis manifesting as a mass lesion, thus, mimicking a lung carcinoma is an unusual radiographic presentation of tuberculosis (TB). The common radiologic patterns and clinical presentations are well known and documented. We report two cases of pulmonary tuberculosis with a neoplastic appearance on chest imaging diagnosed histologically. A 21 - year old female with cough, weight loss, anorexia and an unremarkable physical examination. Chest radiography showed a right apical mass suggestive of lung cancer. Histology of the lesion revealed parenchymal pulmonary tuberculosis. A 49-year old male with left-sided chest pain, cough, anorexia, weight loss, mild pallor with an unremarkable chest examination. Chest imaging showed a left apical mass and mediastinal lymphadenopathy. Microscopic examination of the mass confirmed pulmonary tuberculosis. Pseudotumour pulmonary tuberculosis is a rare clinical entity that can lead to diagnostic challenges and must be considered in the differential diagnosis when mass lesions are seen on chest imaging, especially in TB endemic areas.

Pulmonary Tuberculosis II
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...

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
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.
