Intraventricular craniopharyngiomas: topographical classification and surgical approach selection based on an extensive overview

Abstract

Two different topographies might be considered among IVC: strict and non-strict intraventricular location. Non-strictly IVC have wider and tighter adhesions to third ventricle boundaries and this subtype is associated with a worse outcome.

History before diagnosis in childhood craniopharyngioma: associations with initial presentation and long-term prognosis

“…Table 5 Ten-year overall survival, 10-year progression-free survival, functional capacity (percentiles for FMH ability score), and degree of obesity (BMI SDS (17) significantly the DOH, and CPs causing hydrocephalus are those occupying the third ventricle and expanding toward the Monro foramina. The lack of a significant relationship between the patterns of symptoms and the topography of the lesion in our study could be due to an inadequate topographical scheme of classification, which does not take into account the involvement of the third ventricle compartment or, alternatively, the primary infundibulotuberal development of the lesion (34,35,36,37,38). An accurate discrimination of vital structures such as the infundibulum, the third ventricle floor (tuber cinereum), the third ventricle cavity, and the type and degree of optic chiasm distortion (39) could not be performed due to missing imaging data not available in our retrospective multicenter study.…”

Microscopic versus endoscopic approaches for craniopharyngiomas: choosing the optimal surgical corridor for maximizing extent of resection and complication avoidance using a personalized, tailored approach

“…Various authors have classified craniopharyngiomas based on the location, their relationship to the pituitary stalk, or their position along the vertical hypophyseal axis. 33,53,54 While these classification systems can assist with surgical approach selection, it is important to recognize the limits of such systems, as it is possible for craniopharyngiomas to extend into multiple regions, which increases the surgical complexity. Accordingly, a combined approach using more than one corridor may be necessary for extensive craniopharyngiomas involving multiple anatomical compartments that are not amenable to one isolated approach.…”

Craniopharyngioma recurrence: the impact of tumor topography

“…According to our systematic review of pathological, surgical, and MRI evidence for an accurate definition of CP-third ventricle relationships, CPs originating in the upper neurohypophysis (median eminence) and adjacent basal hypothalamus (tuber cinereum) correspond to the infundibulo-tuberal, or not strictly intraventricular, category-a group of lesions embedded within the hypothalamus itself. [16][17][18][19] In contrast, CPs originating in the pars tuberalis of the pituitary stalk, below an anatomically intact TVF, quite often push against the third ventricle, mimicking an intraventricular location. Hence, we included these seemingly intraventricular lesions in the suprasellar-pseudointraventricular category.…”

“…Hence, we included these seemingly intraventricular lesions in the suprasellar-pseudointraventricular category. [16][17][18][19] From a surgical perspective, a precise distinction between both topographical categories is paramount.…”
