Pure intraventricular craniopharyngioma is a rare subtype of craniopharyngioma that attaches frequently to the hypothalamus. The main challenge in tumor removal is protection of hypothalamic structure. The aim of our study was to set up a feasible risk-evaluation approach to help the surgeons make an individual treatment plan. ⋯ Attachment and deformation grade evaluated based on our criteria are significantly correlated with postoperative outcome. GTR of tightly attached tumor is associated with worse endocrinologic, functional, and radiologic outcomes compared with STR. Hence, we suggest that individual surgical plans should be made according to the grade of tumor attachment and hypothalamic deformation. STR should used in tumors with a high grade to achieve a good long-term outcome and avoid severe postoperative sequelae.

Craniopharyngiomas represent one of the major challenges of neurosurgery. Surgical management of craniopharyngiomas classically required various transcranial approaches with the transsphenoidal route reserved for very selected cases. With the widespread use of endoscopes in endonasal surgery in the past decade, the extended endoscopic endonasal transtuberculum and transplanum approaches have been proposed as an alternative surgical route for removal of different types of suprasellar tumors, including solid craniopharyngiomas in patients with normal pituitary function and small sella. ⋯ The endoscopic endonasal approach offers advantages in the management of craniopharyngiomas that historically have been approached via the transsphenoidal route (i.e., purely intrasellar or intra-suprasellar infradiaphragmatic, preferably cystic lesions in patients with panhypopituitarism). Use of the "extended" endoscopic endonasal approach overcomes the limits of the transsphenoidal route to the sella enabling the management of different purely suprasellar and retrosellar cystic/solid craniopharyngiomas, regardless of the sellar size or pituitary function.

A journey into the technical evolution of neuroendoscopy.
Neuroendoscopy has become a well-accepted technique in neurosurgery. After the introduction of the endoscope in medical practice by Phillip Bozzini in 1806, influential individuals such as Harold Hopkins and Karl Storz paved the way for its current success. ⋯ The importance of each development for the purpose of the instrument is explained. Gaps in the literature regarding the technical aspects of neuroendoscopy, including the optical physics in the endoscope, three-dimensional endoscopy, and clinical applications of neuroendoscopy and robotics, are addressed.

The aim of the study was to examine the correlation between various morphometric factors of the posterior circulation aneurysms and the severity of neurologic status and radiologic extent of subarachnoid hemorrhage. ⋯ Inflow angle and SR were found to be correlated with grading in FRS, and WFNS scale was correlated with inflow angle.

To develop an understanding of the availability of the formal clinical neuro-oncology educational opportunities for medical students. ⋯ Formal clinical neuro-oncology elective opportunities for medical students in the United States and Canada are limited. Additional such opportunities may be of value in the education of medical students.
