Huge Tornwaldt Cyst With Otitis Media With Effusion.

Tornwaldt cyst is a relatively rare lesion that is found in the posterior wall of the nasopharynx. It occurs in the midline bursa of the nasopharynx and represents a persistent communication between the roof of the nasopharynx and the notochordal remnants. Smaller cysts are usually asymptomatic; cysts exceeding a diameter of 1 to 2 cm may be symptomatic. Magnetic resonance imaging is the best imaging modality for diagnosing Tornwaldt cyst. We present a rare case of a huge Tornwaldt cyst completely obstructing the nasopharyngeal airway.
