Abstract
- Bilateral abducens nerve palsy is mediated mainly by increased intracranial pressure, accompaniment to subarachnoid hemorrhage and others, relatively direct involvement of abducens nerve nucleus or its intracranial pathway is unusual case. A 45-year-old male patient complaining of double vision showed isolated bilateral abducens palsy. Cerebral angiography revealed a dissecting aneurysm of the basilar artery. Bilateral abduction deficit has resolved after stent assisted coil embolization. We suggest that basilar artery dissecting aneurysm should be included as a cause of bilateral abducens nerve palsy.
