Although the association between fibromuscular dysplasia (FMD) and intracranial aneurysms is well known, giant aneurysms are rarely encountered in this context. The authors treated two patients with FMD accompanied by giant intracranial aneurysms, one in the left cavernous sinus and the other at the left vertebral artery. Neither patient underwent surgery; with conservative treatment both patients' neurological symptoms abated. The characteristic features of FMD are outlined and various aspects of the association between FMD and intracranial aneurysms are discussed, with particular emphasis on the possible etiology and the treatment of giant aneurysms accompanying FMD.
