What causes a Thornwaldt cyst?

What causes a Thornwaldt cyst?

Tornwaldt cyst or Thornwaldt cyst or Nasopharyngeal cyst represents the remnant of notochord. It is usually small and accidentally diagnosed on MRI. Large sized cyst may presents with nasal, ear or cervical symptoms. Recurrent nasopharyngeal infection and trauma are common etiological factor.

Where is a Thornwaldt cyst?

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 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.

How common are Thornwaldt cysts?

Nasopharyngeal (Tornwaldt’s) cysts are rare and a result of abnormal embryological development at the posterior wall of nasopharynx. Its reported prevalence varies greatly ranging from 1.4% to 3.3% in autopsy series and from 0.2%-5% in MRI series.

Can Thornwaldt cyst be removed?

To diagnose Tornwaldt cyst, doctors insert a flexible viewing tube through the nose (called a nasopharyngoscope). Doctors confirm the Tornwaldt cyst diagnosis with imaging tests, such as a computed tomography (CT) scan or magnetic resonance imaging (MRI). Surgery is done to drain the cyst or remove it.

Can Thornwaldt cyst cause dizziness?

These cysts are generally diagnosed during imaging investigations for symptoms of sore throat, headache, dizziness, seizure, foul oral odor or taste, purulent discharge, or eustachian tube obstruction, all of which may occur due to infection of these cysts [3]. The reported incidence of Tornwaldt’s cysts range from .

How is a Thornwaldt cyst removed?

When the cyst is large, symptomatic, or adjacent to the Eustachian tube orifice, surgery is the choice. The treatment of option for Tc is surgical excision or marsupialization. The root of the Tc can be close to the underlying prevertebral fascia and exact excision would be done under general anesthesia.

Can Tornwaldt cyst cause symptoms?

Tornwaldt’s cyst represents a benign tumor which develops in the midline of the nasopharyngeal mucosa. Due to the fact that it doesn’t usually cause any symptoms, it is often discovered incidentally during a nasal endoscopy or another imaging investigation (either CT or MRI).

How do you treat a Thornwaldt cyst?

1. Since the Thornwaldt cyst is a rare disease and basically asymptomatic, it is not often diagnosed.
2. Established treatment is drainage and marsupialization of the cyst, performed by transoral (by palate elevation) or transpalatine approach for larger cysts.

How do you remove a Thornwaldt cyst?

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.

What kind of disease is Tornwaldt’s disease?

Tornwaldt’s disease. Tornwaldt’s disease is the inflammation or abscess of the embryonic cyst of pharyngeal bursa.

What causes the cyst in Tornwaldt’s disease?

It is bounded posteriorly by longus muscle. The symptoms usually appear when there is inflammation of pharyngeal bursa causing Tornwaldt’s cyst. This is caused by spontaneous drainage in the nasopharyngeal cavity or can also be caused because of involvement of nervous plexus.

What causes the pharyngeal pouch in Tornwaldt’s disease?

Tornwaldt’s disease is a rare benign disorder caused by persistent notochord remnants. This disease almost remains asymptomatic. At about the 10th week of embryonic development, the pharyngeal pouch forms by adhesion of the pharyngeal ectoderm to the cranial end of the notochord.

What is a Tornwaldt cyst in the nasopharynx?

NOTE: This is the Professional Version. Tornwaldt cyst is a rare cyst in the midline of the nasopharynx that may become infected. Tornwaldt cyst is a remnant of the embryonal notochord superficial to the superior constrictor muscle of the pharynx and is covered by the mucous membrane of the nasopharynx.
