CTICasesObstructive Left Upper Lobe Collapse (Carcinoid and Adenocarcinoma)
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
On conventional radiography, there were narrow and abnormally located vessels in the left lung, an elevated left main bronchus, absence or displacement of the left pulmonary artery, an elevated left hemidiaphragm, and subtle anterior chest opacity. CT confirmed left upper lobe volume loss and collapse, with an obstructing tumor in the left upper lobe bronchus.
Key takeaways
This case provides a detailed demonstration of the subtle yet classic radiographic and CT findings of obstructive left upper lobe collapse. It emphasizes the 'art of conventional radiography' in recognizing these changes. Pathologically, two distinct lesions were identified: a carcinoid tumor obstructing the bronchus and a separate adenocarcinoma within the collapsed lobe.
