Cerebral foreign body reaction after carotid aneurysm stenting.

We present a case where we encountered an unusual intracerebral complication several months after endovascular treatment of a large left internal carotid artery aneurysm, and where brain biopsy revealed foreign body reaction to hydrophilic polymer fragments distally to the stent site. Although previously described, embolization of polymer material from intravascular equipment is rare. We could not identify any other biopsy verified case in the literature, with this particular presentation of intracerebral polymer embolization - a multifocal inflammation spread out through the white matter of one hemisphere without hemorrhage or ischemic changes.
