A Rathke's cleft cyst is a benign growth on the pituitary gland in the brain, specifically a mucin-filled [1] cyst in the posterior portion of the anterior pituitary gland. [ 2 ] [ 3 ] It occurs when the Rathke's pouch does not develop properly and ranges in size from 2 to 40 mm in diameter.
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. [1] Sometimes nasopharyngeal cyst may directly refer to Tornwaldt cyst. [2]
Rathke's pouch is a sac-like structure that gives rise to the pars distalis, pars intermedia, and pars tuberalis of the pituitary gland. The cells of Rathke's pouch proliferate and differentiate into various hormone-producing cells, including Somatotrophs, Lactotrophs, Corticotrophs, Thyrotrophs, and Gonadotrophs.
Alternative diagnoses for CCRN consist of thyroglossal duct cyst, hair follicle naevus, fibroepithelial polyp, and branchial cleft cyst. [6] Thyroglossal duct cysts are typically found in the midline of the neck, near the hyoid bone, and move with tongue protrusion or swallowing. [7]

Craniopharyngioma is a rare, usually suprasellar [15] neoplasm, which may be cystic, that develops from nests of epithelium derived from Rathke's pouch. [16] [17] Rathke's pouch is an embryonic precursor of the anterior pituitary. [citation needed] Craniopharyngiomas are typically very slow-growing tumors.
Cerebroretinal microangiopathy with calcifications and cysts (CRMCC) is a rare genetic disorder, which affects multiple organs. [ 1 ] [ 2 ] Its hallmarks are widespread progressive calcifications , cysts and abnormalities of the white matter of the brain, usually occurring together with abnormalities of the blood vessels of the retina .
These account for 8% of the sinuses and cysts of the neck. They are lateral to the facial nerve and run parallel to the external auditory canal. [9] Second branchial cleft cysts - These account for 90 to 95% of the neck cysts. Anterior to sternocleidomastoid muscle, posterior to submandibular gland, lateral to carotid sheath. They are medial to ...
