- Large well-defined extra-pulmonary subcarinal non-enhancing cystic mass having an average density of 28 HU (likely due to the proteinaceous contents).
- Non–calcified
- Thin imperceptible walls
- Splaying of the carina and mass effect over the main bronchus.
-
These radiological features are suggestive of a bronchogenic cyst.
Imaging differential diagnoses include esophageal duplication cyst, and pericardial cyst.

Subcarinal lesion seen on previous chest radiograph and CT chest is no longer appreciable.
Case Discussion
The lesion was resected.
Histopathology: Cyst lined by ciliated respiratory-type epithelium with subepithelial seromucous glands and smooth muscle, consistent with a bronchogenic cyst.
