Disappearance of a tumor shadow fed by the tentorial artery after embolization of the external carotid artery.
The tentorial artery is a branch of the meningohypophyseal trunk originating from the internal carotid artery; this artery sometimes becomes an enlarged feeding artery in patients with tentorial lesions, especially tentorial meningiomas. We experienced a case of a cerebellopontile angle meningioma whose angiogram revealed the disappearance of a feeding artery arising from the tentorial artery after embolization of the external carotid artery. We report this case and discuss the mechanism of this phenomenon.
