|Text||bursa pharyngea, pharyngeal bursa, bursa pharyngealis:
an inconstant blind sac located above the pharyngeal tonsil in the midline of the posterior wall of the nasopharynx; it represents persistence of an embryonic communication between the anterior tip of the notochord and the roof of the pharynx. Called also Luschka's b., Tornwaldt's b., and Tornwaldt's cyst.
from Dorland's Medical Dictionary
NOTE: Dr. Tornwald spelled his own name without the "h". However, the published literature uses both "Tornwaldt" and "Thornwaldt".

Is that another Thornwaldt's cyst on M.R.I.?
Battino RA, Khangure MS.
20% of 200 M.R.I. head scans displayed increased signal in the midline posterior-superior nasopharynx in the position of the pharyngeal bursa. Though these likely represent a number of different entities, Thornwaldt's cysts may be more common than previously realised.

Radiology of the nasopharynx: pictorial essay.
Chong VF, Fan YF.
The nasopharynx, located just below the central skull base, is a difficult area to evaluate clinically. Endoscopic examination provides useful information but cannot delineate submucosal disease. Benign lesions of the nasopharynx are relatively uncommon. They include Thornwaldt cyst, juvenile angiofibroma, haemangioma, haemangiopericytoma, Kimura's disease, branchial cleft cyst, oncocytoma, amyloidoma, and non-ossifying fibromyxoid tumours. The most common malignant lesions are carcinomas and lymphomas. Other malignant neoplasms such as adenocystic carcinomas are rarely seen. The purpose of the present pictorial review is to highlight the salient normal anatomy of the nasopharynx and the spectrum of pathological anatomy.

Huge Thornwaldt's cyst: a case report.
Lin JH, Tai CF, Lee KW, Ho KY, Kuo WR, Wang LF.
Thornwaldt's bursa, also known as nasopharyngeal bursa, is a recess in the midline of the nasopharynx that is produced by persistent notochord remnants. If its opening becomes obstructed, possibly due to infection or a complication from adenoidectomy, a Thornwaldt's cyst might develop. Here, we present a 53-year-old man who complained of nasal obstruction that had progressed for 1 year. Nasopharyngoscopy showed a huge nasopharyngeal mass. Thornwaldt's cyst was suspected. Magnetic resonance imaging showed a lesion measuring 3.6 x 3.4 cm, intermediate on T1-weighted and high signal intensity on T2-weighted imaging, neither bony destruction nor connection to the brain. The patient underwent endoscopic surgery for this huge mass. Afterwards, his symptoms improved significantly. We present the treatment and differential diagnosis of a nasopharyngeal cyst.

The diagnosis of Thornwaldt's cyst.
Boucher RM, Hendrix RA, Guttenplan MD.
Thornwaldt's cyst is an uncommon nasopharyngeal lesion which develops from the remnant of the primitive notochord. A case report of a patient with a Thornwaldt's cyst and cervical adenitis is presented. Though computed tomography of the head and neck was unremarkable, magnetic resonance imaging of the nasopharynx revealed the Thornwaldt's cyst, suggesting that this modality may be more sensitive in detecting and evaluating cystic lesions of the nasopharynx. The differential diagnosis of cystic nasopharyngeal masses is discussed.

Imaging of nasopharyngeal cysts and bursae.
Ben Salem D, Duvillard C, Assous D, Ballester M, Kraus–Ļ D, Ricolfi F.
Cysts and bursae of the nasopharynx are uncommon and seldom symptomatic when compared with malignant tumors of this region. However, it is noteworthy that in the presence of symptoms, a good knowledge of their radiological appearance is useful to establish the correct diagnosis. Cysts of Rathke's pouch, pharyngeal bursa of Luschka, Tornwaldt's cysts, retentional cysts of the seromucinous glands, oncocytic cysts, intra-adenoid cysts, branchial cysts, prevertebral or retropharyngeal abscess and pseudocysts of the nasopharynx will be discussed in this paper.
