Bronchoscopic view of post-tuberculosis lung cavity: A case report

An elderly male, a former smoker, was evaluated at the pulmonary medicine clinic for recurrent episodes of streaky hemoptysis for the last 3 years. He had a history of being successfully treated for microbiologically confirmed pulmonary tuberculosis in the past. He presented in this consultation with two episodes of large volume hemoptysis, and the laboratory results suggested an ongoing active infection. Sputum smear was negative for an infectious etiology. Contrast-enhanced CT of the thorax revealed a lung cavity in the right upper lobe. He underwent flexible bronchoscopy with bronchoalveolar lavage which revealed Klebsiella pneumoniae infection. Small-diameter bronchoscope was used to navigate into the affected lung segment which revealed a cave-like appearance. This was an interesting finding and physicians should be familiar with such bronchoscopic findings and techniques in the management of their patients, particularly in tuberculosis endemic areas.
