| Summary: | Four patients with active pulmonary tuberculosis (PTB) presenting with respiratory failure are reported here. Bronchogenic PTB, simulating an acute febrile illness or diffuse interstitial lung disease with short duration of symptoms, as a cause of acute respiratory failure is less recognized. If diagnosed and treated early, it has good prognosis. Three of the four patients presented here had an acute presentation with fever, dyspnoea, and hypoxemia with diffuse infiltrative lesions on radiography, and the other younger patient presented predominantly with lobar consolidation. These patients presenting with respiratory failure required intensive care management, and a diagnosis was made with bronchoalveolar lavage fluid and transbronchial lung biopsy. All four patients promptly received antitubercular therapy, showed clinicoradiological improvement, and were stable at 1 year follow up.
