Abstract

Objective: We herein report a rare case of primitive trigeminal artery variant (PTAv) aneurysm presenting with abducens nerve palsy.
Case presentation: A 61yearold female had suffered from diplopia of her left lateral gaze for seven days due to left abducens nerve palsy. Left carotid angiography showed a PTAv trunk aneurysm. Internal trapping of the aneurysm with detachable coils was performed. The left abducens nerve palsy thereafter showed a remarkable improvement and disappeared completely.
Conclusion: Only six previously reported cases of PTAv were associated with an aneurysm of the PTAv. Two of the six cases presented with abducens nerve palsy. We therefore consider coil embolization of PTAv aneurysms to be a useful treatment, even if the patient presents with abducens nerve palsy.
