The CXR shows severe volume loss and calcification in the left upper lobe consistent with previous tuberculosis. In addition, there is widespread calcification of the mediastinal lymph nodes. In rare instances, a calcified lymph node can erode into the airway causing hemoptysis or obstruction, as shown on CT (Fig 92.2). This condition is called broncholithiasis and can be demonstrated on CT or flexible bronchoscopy. Bronchoscopic removal of the broncholith may be attempted.
