Imaging findings
The patient presented with a persistent right lower lobe opacity that was followed across several imaging studies. Closer evaluation revealed an endobronchial component within the bronchus, which had been previously overlooked. This feature, described as an iceberg-type phenomenon with subtle internal calcifications, was consistent with a carcinoid tumor, which was later confirmed by bronchoscopy.
Key takeaways
When evaluating persistent lower lobe opacities, always consider a carcinoid tumor. The endobronchial component may be subtle and can be easily overlooked if more obvious inflammatory changes are present, emphasizing the need to scrutinize the airways in any patient with a persistent opacity.
