A middle-aged, non-smoker male presented with exertional breathlessness and occasional productive cough for last two years. He had successfully completed anti-tuberculosis treatment twice in the past for microbiologically confirmed drug-sensitive pulmonary tuberculosis (TB). Upon consultation at our centre, the patient was sputum negative and imaging was suggestive of destroyed lung on the right side. Spirometry revealed airflow obstruction, and a diagnosis of post-tuberculosis obstructive lung disease was rendered. As part of an Institutional Ethics Committee-approved post-doctoral thesis protocol, this patient underwent a bronchoscopic airway evaluation wherein an unusual bronchoscopic appearance of post-tuberculosis destroyed lung was noted. We named this as the ‘haunted cave sign’ and believe Pulmonologists should be familiar with this appearance and its significance to ensure correct identification, given its common occurrence in high-burden TB endemic countries.
