Sensory Neural Hearing Loss

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.
Key words : vertebral artery aneurysm, sensory neural hearing loss, ABR, MRI
