If the opening through which the bursa drains into the nasopharynx becomes obstructed, a Thornwaldt's cyst (TC) might develop.

So it was a Thornwaldt's cyst opened due to the impact of coconut fall over the head.
Thornwaldt's bursa or nasopharyngeal bursa is a recess in the midline of posterosuperior wall of nasopharynx, formed from notochordal remnant.
cysts represent benign congenital lesions that arise in the midline of the nasopharynx, seen in approximately 0.2% to 5% of the population on MRI studies.
The differential diagnosis of a nasopharyngeal cyst, clinically and by imaging, should include Thornwaldt
cyst, abscess, sphenoid sinus mucocele, choanal polyp, encephalocele, and benign mixed tumor.
's cyst also known as pharyngeal bursa, is a rare midline cyst found in the nasopharynx.
The differential diagnosis of choanal polyp includes hypertrophied adenoid, angiofibroma, Thornwaldt
cyst, pituitary tumor, lymphoma, and carcinoma.
(2) It has been spelled Thornwaldt
in some publications, (3-6) but Tornwaldt is correct.
Tornwaldt's cysts (sometimes called Thornwaldt
's cysts) develop as a result of abnormal embryologic development at the posterior wall of the nasopharynx.
Differential diagnoses include antrochoanal polyp, hypertrophied adenoids, thornwaldt
's s cyst, pituitary tumor, lymphoma, and carcinoma.
(9) Mucosa of nasopharynx is composed of epithelium, lymphoid tissue and accessory salivary glands therefore d/d include rathke's pouch, pharyngeal bursa, teratoma, meningocele, abscess, meningocele, ac polyp, mucocele of sphenoid, JNA, pleomorphic adenoma D/d of Thornwaldts
cyst and Branchial cyst is based on the anatomical location.
