Broncholithiasis is an uncommon airway disease. It presents as calcified material in or adjacent to the tracheobronchial trees due to extrusion and erosion of the calcified lymph nodes into the airway. Calcified lymphadenitis due to mycobacterial infections is the most important cause of broncholithiasis, and may lead to airway obstruction. Here, we reported a patient who had calcified subcarinal lymph nodes 3 years ago on chest computed tomography. She was admitted to our hospital this time with the finding of calcified lymphadenitis in the left main bronchus, causing obstruction. The calcified lymphadenitis was successfully removed by flexible bronchoscopy, with basket.
