title: Postembolization perianeurysmal edema as a cause of uncinate seizures.
abstract: We report a patient with a giant unruptured supraclinoid aneurysm treated by endovascular embolization by means of bare coils and implantation of a flow diverterstent. Eight weeks after the embolization, she presented with uncinate seizures. Neuroradiological examination revealed de novo postembolization perianeurysmal edema, which has been described only rarely. A brief course of oral steroids successfully controlled the seizures. Perianeurysmal edema must be considered a potential complication after embolization of large aneurysms with coils and other means, and needs to be considered as a differential diagnosis in patients with unusual neurological symptoms at either the acute or delayed stages. To our knowledge, this is the first report of postembolization perianeurysmal edema occurring after successful occlusion by means of bare coils and a flow diverterstent. This report contributes to the growing evidence on adverse post-coiling inflammatory reactions, and specifically on perianeurysmal edema.
