Post-traumatic pituitary stalk transection syndrome (PSTS) is an extremely rare cause of combined pituitary hormone deficiency (CPHD), affecting approximately 9 per 100,000 cases of traumatic brain injury. In contrast, pituitary stalk interruption syndrome (PSIS) is also a rare cause of CPHD. Importantly, these conditions are often confused due to their similar names and resembling findings on magnetic resonance imaging (MRI).

Similarly, tumor extension into the interpeduncular and retrosellar space poses a major surgical challenge. Pituitary transposition techniques have been developed to gain additional access.

Background And Objectives: Craniopharyngiomas originate from the pituitary stalk (PS) and extend along the pituitary-hypothalamic axis. Peripheral retroinfundibular craniopharyngiomas, particularly, may have worse surgery outcomes than other types. This study aims to investigate the advantage of using "one-and-a-half" interdural transcavernous pituitary transposition/rotation to dissect the tumor from the residual stalk and hypophyseal portal system for this subtype of craniopharyngioma.

Neurosurgery, Heping Hospital Affiliated to Changzhi Medical College, Changzhi City, Shanxi Province, China.
This paper studied the arachnoid of the chiasmatic cistern (CC) and the methods for increasing the exposure of the CC from an endoscopic perspective. Eight anatomical specimens with vascular injection were used for endoscopic endonasal dissection. The anatomical characteristics of the CC were studied and documented, and anatomical measurements were collected.

Purpose: The histopathological study of brain tissue is a common method in neuroscience. However, efficient procedures to preserve the intact hypothalamic-pituitary brain specimens are not available in mice for histopathological study.
Method: We describe a detailed procedure for obtaining mouse brain with pituitary-hypothalamus continuity.
