Perianeurysmal edema in giant intracranial aneurysms in relation to aneurysm location, size, and partial thrombosis

Abstract

Perianeurysmal edema was associated with GIA size and the presence of PT. As no PAE was observed in cavernous ICA aneurysms, even though they exerted mass effect on the brain and also displayed PT, the dura mater may serve as a barrier protecting the brain from PAE formation.
