Imaging findings
A 50-year-old male presented for lung cancer screening. A coronal thick-section mean image (pseudo chest X-ray) showed volume loss on the right, with clear obstruction of the bronchus intermedius. Further CT confirmed an endobronchial lesion.
Key takeaways
This was the most dramatic lung cancer seen on a screening CT, clearly indicating an obstructing endobronchial lesion. It was categorized as a Lung-RADS 4B with an X modifier, with near-certainty of malignancy. PET confirmed a hypermetabolic lesion, which turned out to be squamous cell carcinoma. Despite the extensive findings, the patient's symptoms were minimal, with only slight hemoptysis and shortness of breath.
