FIG 5. Mannitol embolization of a large frontal meningioma.
A, Tumor vessels coming off the left middle meningeal artery are shown by this early arterial phase of left external carotid angiogram.
B, The capillary phase of the same angiogram reveals the typical tumor blush in the meningioma.
C, Postembolization angiogram of the left external carotid artery shows lack of filling of the tumor vessels in the early arterial phase.
D, Most of the tumor blush has been eliminated and contrast stagnation is seen in one of the middle meningeal branch in the delayed phase.
