Imaging reveals innumerable pulmonary nodules (arrows) with mediastinal, bilateral hilar, and subcarinal lymphadenopathy (asterisk). C Middle-aged man presents with hemoptysis and dyspnea. Imaging reveals endobronchial disease in the right main bronchus at the level of the carina (arrowhead), moderate pleural effusion (P), and lung mass (arrow). D Middle-aged man with chronic myeloid leukemia on imatinib transferred for airway exacerbation.
