Abstract:
A 69-year-old man with a history of pulmonary tuberculosis presented with fever. He tested positive for the QuantiFERON TB-2G and human T-cell lymphotropic virus type 1 antibodies. Imaging revealed a mass in the neck of the gallbladder, with periportal lymph node enlargement and penetration into the duodenum. A definite diagnosis could not be made, even with a subsequent detailed examination. Finally, cholecystectomy and a lymph node biopsy were performed. Histopathology revealed a caseating granuloma in the lymph nodes and in the serosa of the gallbladder, and polymerase chain reaction was positive for tuberculosis. Therefore, the patient was diagnosed with abdominal tuberculosis lymphadenitis extending into the gallbladder and duodenum.

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.
