CTICasesBilateral Bronchogenic Cysts
Imaging findings
CT chest and scout view show two distinct mediastinal masses flanking the trachea and main bronchi. The right-sided mass behind the bronchus intermedius shows fluid attenuation, while the left-sided mass is intermediate/high attenuation, representing high proteinaceous content. MRI confirms fluid-like T2 hyperintensity in both.
Key takeaways
Bilateral bronchogenic cysts are rare congenital foregut duplication anomalies. They can demonstrate variable CT attenuation due to differences in protein, calcium, or mucus content, but MRI is helpful to confirm their cystic nature.
