急性感音難聴で発症した椎骨動脈瘤例

抄録

Although vertebral artery aneurysm is uncommon, its rupture causes subarachnoid hemorrhage (SAH). It commenced with tinnitus, and hearing loss advanced during medical treatment as acute sensory neural healing loss. As ABR was revealed as only a wave I extension, MRI was performed. A well enhanced Cerebello pontain angle tumor was shown, and the aneurysm was found in the four vessel study.
The aneurysm was embolized using GDC coils and hearing loss advanced to deafness. It was thought that the unruptured aneurysm was enlarged and put pressure on the acoustic nerve.
