pertaining to the cranium and pharynx.

craniopharyngeal duct
the primordial outgrowth from the roof of the pharynx from which the posterior lobe of the pituitary gland is formed; a vestigial structure in most species; see also rathke's pouch.
craniopharyngeal duct cyst
cysts from remnants of the distal craniopharyngeal duct are found close to the pituitary gland. Pressure on the gland and inflammation and subsequent fibrosis of it can cause a syndrome of adenohypophyseal hypofunction. There may be blindness, obesity and diabetes insipidus. Brachyocephalic breeds of dogs are predisposed.

They were named by Harvey Cushing and described as being derived from "epithelial rests ascribable to an imperfect closure of the hypophysial or craniopharyngeal duct".
It is supposed to develop owing to transformation of embryonic squamous cell structures along the path of the craniopharyngeal duct.
Their localization can be intrasellar, suprasellar or parasellar and basically anywhere alongside the craniopharyngeal canal [1, 2].
More than 40 years later, in 1899, Mott and Barett hypothesized that tumor originated from the cells of embryonic epithelial remnants of craniopharyngeal canal, while Lewis in 1910 published the first attempt of its surgical removal.
In 1904, Erdheim postulated that craniopharyngiomas developed from squamous remnants of the obliterated craniopharyngeal duct, suggesting that these tumors may arise at any point along the tract of migration of Rathke's pouch from the vomer, the roof of the nasopharynx, or through the midline sphenoid bone beneath the floor of the sella turcica.
Hypothalamic hamartoma associated with a craniopharyngeal canal.
The medial aspect of the temporal bone may fail to develop, resulting in a persistent lateral craniopharyngeal canal (also known as the Sternberg canal) between the middle cranial fossa and the pneumatised inferolateral recess of the sphenoid sinus.
The index case was observed earlier in the year than in previous years, and clinical manifestations of the cases were unusual (absence of craniopharyngeal syndrome and bleeding from gastrointestinal tract that are typical for CCHF patients from Bulgaria); in the fatal case, autopsy of the patient showed hemorrhages only in the lungs.
Craniopharyngiomas arise from remnants of Rathke's pouch along the path of the craniopharyngeal canal.
Transsphenoidal encephaloceles have often been attributed to persistence of the craniopharyngeal canal.
The etiology of the craniopharyngeal canal is unknown, although two theories have been proposed to explain its origin.
Craniopharyngiomas are suprasellar tumours that are believed to arise from craniopharyngeal duct remnants.
