CTICasesInfected Bronchogenic Cyst
Imaging findings
Chest CT and MRI demonstrate a large, heterogeneous, thick-walled anterior mediastinal mass with surrounding fat stranding and bilateral pleural effusions. MRI shows internal loculations with varying fluid signals (pus and blood), resembling an abscess.
Key takeaways
Bronchogenic cysts can rarely become infected and present as painful anterior mediastinal masses that mimic abscesses or necrotizing tumors on CT and MRI, featuring wall thickening, heterogeneous fluid signal, and surrounding inflammatory stranding.
