Spontaneous regression of an unruptured and non-giant intracranial aneurysm

Abstract

It is well known that spontaneous thrombosis in giant cerebral aneurysm is common. However, spontaneous obliteration of a non-giant and unrup-tured cerebral aneurysm has been reported to be rare and its pathogenic mechanism is not clear. We describe a case with rare vascular phenomenon and review the relevant literatures. © 2012 The Korean Neurosurgical Society.
