Thornwaldt's cyst is a rare cyst like lesion located in the posterior wall of the nasopharynx. It is usually a developmental abnormality where communication between pharyngeal endoderm and notochordal remnents persist. If symptomatic they cause nasal obstruction, nasal regurgitation , postnasal drip or . occipital headache . Nasal endoscopy is the easiest way to visualize this during a routine ENT examination. If in any doubt, MRI is the most sensitive method for detecting and evaluationg the cyst. The cyst is usually hyperintense in T2 weighted images. Surgery by marsupialization is the treatment option.
