Tuberculosis remains the world’s leading infectious cause of death — and one of the densest, most testable topics across NEET-PG, NEET-SS, and AIIMS. This comprehensive clinical review walks through the entire spectrum: massive haemoptysis and Rasmussen’s aneurysm, every site of extrapulmonary TB from lymph nodes to congenital liver seeding, the full diagnostic algorithm with CBNAAT and culture, drug-sensitive and MDR/XDR regimens with mechanism-level pharmacology, and high-yield distinctions like Ghon focus vs Ranke complex. The booklet closes with 10 AIIMS-level clinical MCQs with detailed reasoning. Designed for the practising physician — and for the candidate sitting tomorrow’s exam.
