[Super-selective catheterization and embolization of the arterial pedicles of 2 meningiomas of the posterior fossa].
In two cases with meningioma in the posterior fossa, the angiographic study, completed with the super-selective catheterization of the main pedicles, was followed by the technic of embolization. In the first case, a large meningioma, extending from the clivus to the left cerebello pontine angle, was supplied mainly by the ascending pharyngeal artery. In the second case, a huge meningioma, originating from the left inferior tentorial surface, was irrigated predominantly through the posterior branch of the middle meningeal artery and through the left occipital artery. Super-selective catheterization allowed us to better know in both cases the tumoral vasculature and to identify precisely the territory nourished by each supplying artery, from the external carotid artery.
