Fig.4. Meningioma of medial segments of the sphenoid bone wings: Preoperative embolization.

A - left-side carotid angiogram: A tumor vascular network fills from the meningohypophyseal trunk.
B - a capillary phase of angiogram: The own vascular network of a tumor.
C, D - selective angiogram of the left ICA in balloon-occlusion of its cavernous segment before embolization of a tumor vascular network.
E, F - selective angiogram of the left ICA in balloon-occlusion and after restoration of flow, following embolization of a tumor vascular network (TruFill 45-150m): A vascular network does not fill.
G, H - MRI of the brain with enhancement after embolization: Degeneration foci in a central part of a tumor.
