What is a Thornwaldt cyst
Isabella Turner
Updated on April 04, 2026
Thornwaldt cysts are rare and benign congenital cysts in the region of the pharyngeal bursa, formed by a communication between the notochord and the nasopharyngeal endoderm. They result from a mechanical obstruction, inflammation, or abscess of the pharyngeal bursa.
What causes Thornwaldt cyst?
The symptoms usually appear when there is inflammation of pharyngeal bursa causing Tornwaldt cyst. This is caused by spontaneous drainage in the nasopharyngeal cavity or because of involvement of nervous plexus.
Is Thornwaldt cyst a tumor?
Tornwaldt’s cyst is a benign tumour, usually located in the midline of the posterior nasopharyngeal wall. MRI is considered the best imaging examination to diagnose this inflammatory benign cyst. It is commonly asymptomatic and requires no treatment.
How is a Thornwaldt cyst treated?
When the lesion is large, symptomatic or close to the Eustachian tube torus, surgery by marsupialization is the treatment option. For small lesions, the endonasal approach is recommended but for large lesions, a transoral retrovelar approach using a 70 degree telescope is the method of choice.How rare is a Thornwaldt cyst?
Introduction. Tornwaldt cyst (TC) is a relatively rare but benign disease. It is a developmental lesion within the midline of the nasopharynx [1]. An incidence of 1.4–3.3% was reported by some authors in the literature [2,3].
Can a Tornwaldt cyst cause seizures?
If these cysts get larger in size or become infected, a variety of symptoms can manifest. These include occipital headache, seizures, dizziness/vertigo, pharyngeal discomfort, estuation tube dysfunction, pharyngitis, halitosis and post nasal drip [,,,].
What is considered a large Thornwaldt cyst?
Most cysts are small, measuring less than 1 cm in diameter and are discovered incidentally. Some are larger, causing nasal obstruction, snoring, halitosis, clearing of the throat, eustachian tube dysfunction, and a feeling of ear fullness.
What is a Thornwaldt Bursa?
Thornwaldt’s bursa, also known as nasopharyngeal bursa, is a recess in the midline of the nasopharynx, which is produced by persistent notochord remnants. If the opening of the bursa is occluded, benign midline nasopharyngeal mucosal cyst called Thornwaldt cyst develops. Thornwaldt cysts are almost always asymptomatic.Where is a Thornwaldt cyst located?
Thornwaldt cysts are developmental benign cysts that present in the midline within the nasopharynx. There is a persistent communication between the roof of the nasopharynx and the notochord.
What is done when a nasopharyngeal cyst is found?Most cysts are small and asymptomatic, but if they grow or become infected, they may cause nasal obstruction, postnasal drip, halitosis, occipital headache, neck stiffness and eustachian tube dysfunction. When the cyst is large or symptomatic, surgery by excision or marsupialization is the treatment option.

Nasopharyngeal cyst refers to cystic swelling arising from midline and lateral wall of the nasopharynx. The commonest cyst arising from lateral wall is the nasopharyngeal branchial cyst, whereas the mucus retention cysts are the commonest to arise from the midline.
What does Marsupialization mean in medical terms?
Marsupialization is a surgical procedure that removes cysts in a way that makes them less likely to return. Once the cyst has been opened and drained, the edges are sutured together to form a permanently open “pocket” or “pouch” that allows fluid to drain easily.
