2024年5月5日 · Persistent hypophyseal canal, also known as the craniopharyngeal canal when larger than 1.5 mm in diameter, is a rare congenital defect characterized by communication through the central skull base between the nasopharynx and the pituitary fossa.

2014年4月1日 · BACKGROUND AND PURPOSE: The craniopharyngeal canal is a rare, well-corticated defect through the midline of the sphenoid bone from the sellar floor to the anterosuperior nasopharyngeal roof. We reviewed a series of craniopharyngeal canals to determine a system of classification that might better our …

2002年5月30日 · Synonyms: hypophyseal canal, craniopharyngeal duct, transsphenoidal canal. Prevalence: very rare. Definition: Persistence of the craniopharyngeal canal is a rare basal skull congenital defect with a range from small canals (in 0.42% of the asymptomatic population [1] ) to large basal cephalocele with major craniofacial defects. Craniopharyngeal ...

A persistent craniopharyngeal canal (CPC) is a rare embryologic remnant that presents as a well-corticated defect of the midline sphenoid body extending from the sellar floor to the nasopharynx. It is thought that the structure either results from incomplete closure of Rathke's pouch or is a former vascular channel remaining from ossification ...

2014年5月29日 · Two cases with a broad persistent hypophyseal canal connecting pituitary fossa and nasopharynx are presented. Both had nasopharyngeal surgery in early childhood and presented later with hypopituitarism. Coronal CT demonstrated the defects with no visible pituitary tissue. The spectrum of basal skull defects is discussed.

The persistent hypophyseal (craniopharyngeal) canal is a rare congenital skull base defect. It extends from the floor of the sella turcica to the nasopharynx and is less than 1.5 mm in diameter. The term craniopharyngeal canal is also used to describe a rarer and much larger bony canal in the same location, which has been referred to as the ...

Persistent craniopharyngeal canal (PCC) is a rare congenital anomaly that appears as a linear well-corticated canal running from the sella through the clivus and into the nasopharynx. Case reports of this anomaly have shown it is associated with a range of craniofacial defects, pituitary abnormalities, and meningoencephaloceles.

2019年11月27日 · We present a case with the persistent hypophyseal canal, and ectopic pituitary teratoma in the nasopharynx. To our knowledge, our patient is the first reported case with this association. Aetiology is unknown; some authors have …

The term “craniopharyngeal canal” or “per-sistent hypophyseal canal” is generally used to describe a small and vertical midline defect in the skull base that measures less than 1.5 mm in diameter. Its incidence in adults has been re-ported as 0.42% [2]. Because of its small size, the craniopharyngeal canal is rarely seen on
