RT Journal Article SR Electronic T1 Multiple cerebral aneurysms in identical twins. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 973 OP 976 VO 18 IS 5 A1 Hagen, T A1 Neidl, K A1 Piepgras, U YR 1997 UL http://www.ajnr.org/content/18/5/973.abstract AB We report the finding of multiple cerebral aneurysms in a pair of identical twins. One twin had subarachnoid hemorrhage and intracerebral hematoma; her sister had subarachnoid hemorrhage and intraventricular bleeding. Angiography in both cases showed multiple cerebral aneurysms. It is appropriate to recommend a cerebral angiographic examination of an asymptomatic twin after the other twin has suffered an aneurysmal subarachnoid hemorrhage.
