Abstract:
A 54-year-old male presented with a large, left-sided hemorrhagic exudative pleural effusion characterized by lymphocytic predominance and a low adenosine deaminase (ADA) level. A pleural biopsy was performed via medical thoracoscopy. The results of histopathology and GeneXpert-MTB/RIF (Mycobacterium tuberculosis/Rifampicin) (Cepheid, Sunnyvale, California, USA) were inconclusive. PET-CT imaging revealed heightened metabolic activity in the mediastinal lymph nodes, further supported by endobronchial ultrasound (EBUS) and transbronchial needle aspiration (TBNA), showing granulomatous lymphadenitis with caseous necrosis. The patient was diagnosed with tuberculous pleural effusion and showed clinical improvement after initiating anti-tubercular therapy.

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.

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...

Pulmonary Tuberculosis IV
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 V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
