Hi.Thanks for posting on HCM.
Thornwaldt's cyst is a relatively rare seen in nasopharynx
. Most are small and asymptomatic whereas some cause nasal obstruction
, postnasal drip, occipital headache
or Eustachian tube dysfunction
. 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 evaluating its size, its anatomic relationships and its content. When the lesion is large, symptomatic or close to the Eustachian tube -surgery by marsupialization is the treatment option. For small lesions advance techniques have minimal trauma and bleeding and excellent postoperative results.I suggest you to take the opinion of ENT specialist
for further management.Hope this helps.Take care.
