HEMORRHAGIC COMPLICATIONS IN EMBOLIZATION OF A MENINGIOMA - CASE-REPORT AND REVIEW OF THE LITERATURE

We report a case of hemorrhage in a parasellar meningioma shortly afte r embolization of the dural cavernous carotid artery branches supplyin g the tumor. This represents the first report of hemorrhage within a m eningioma resulting from embolization with small (50- to 150-mu m) pol yvinyl alcohol particles, as well as the first reported case of hemorr hage complicating meningioma embolization from internal rather than ex ternal carotid artery branch embolization. We also review previously r eported cases of postembolization hemorrhage from meningiomas.
