Initially, she had shortness of breath only on exertion, which progressed to rest over the past 7 days. She reported a loss of appetite and a 10 kg weight loss in 1 month. There was no history of cough, haemoptysis, palpitations, cyanosis, oedema, syncope, orthopnoea and paroxysmal nocturnal dyspnoea associated with breathlessness.Platypnoea–orthodeoxia syndrome refers to shortness of breath and oxygen desaturation in an upright position. Ventilation/perfusion mismatch is a rare cause of the same. Herein, we report a case of bilateral lower lobe tuberculosis, causing platypnoea and orthodeoxia. https://bit.ly/3jhJEQ1 ER -
