Intraventricular meningioma outcome

Intraventricular meningiomas have a favorable prognosis because 90% of them are WHO grade I ¹⁾.

These tumors accounted for a mortality rate of 4.0% (25 deaths) and a recurrence rate of 5.3% (26 recurrences).

Recurrence and mortality were lower than in other localizations likely due to a complete surgical resection rate than in the convexity and skull base, which suggests that GTR is the gold standard for the management of IVMs ²⁾.
