CTICasesTypical bronchial carcinoid tumor causing recurrent pneumonia
Imaging findings
Serial radiographs over 4 months show recurrent left lower lobe pneumonias. CT scan demonstrates a well-defined endobronchial mass obstructing the left lower lobe basal segmental bronchi, with distal post-obstructive atelectasis and consolidation.
Key takeaways
Endobronchial typical carcinoids are slow-growing neuroendocrine tumors that commonly present in young adults with recurrent pneumonia or wheezing in the same anatomical location. Delayed diagnosis is common as radiographs may show transient clearance of post-obstructive fluid.
