Growing Basilar Artery Bifurcation Area Aneurysm: Case Report

ABSTRACT

The authors present the case of basilar artery bifurcation area aneurysm showing the growth of sac. A 46-year-old man was admitted for evaluation of fluctuating dysarthria. He had a history of lacunar infarction 3 years ago. The cerebral angiogram, taken at that time, showed a small aneurysm on basilar artery bifurcation area. Surgical intervention was not performed because of its small size. Brain MRI, taken for evaluation of dysarthria, showed large signal void at the basilar artery bifurcation area and following cerebral angiogram revealed the growth of previous aneurysm in its size. This observation suggests that careful follow-up examination should be performed for incidental small sized aneurysm.
