Imaging findings
Outpatient chest radiography shows a subtle, irregularly shaped opacity beneath the left main bronchus. Chest CT confirms a rounded, vascular, endobronchial mass in the superior segment of the left lower lobe, causing adjacent lung atelectasis. Bronchoscopy correlates with a highly vascular, smooth lobulated mass that nearly completely occludes the bronchial lumen.
Key takeaways
Bronchial carcinoids are slow-growing, highly vascular neuroendocrine tumors that often present as endobronchial masses. They frequently present with recurrent post-obstructive pneumonia or hemoptysis, but can be discovered incidentally on radiographs as subtle subcarinal or retrocardiac opacities.
