Incidental Finding of a Fenestrated Vertebrobasilar Junction Aneurysm

Abstract

We report the case of a sacculara neurysm of the fenestrated vertebrobasilar junction in a 57-year-old woman, incidentally discovered. The diagnosis was made on CT brain angiography which found the an atomical variant and the aneurysm. Vertebrobasilar junction aneurysms are uncommon but often associated with a fenestration of the basilar artery. We detail the radiological features illustrating this association.
