Peripheral Ophthalmic Artery Aneurysm Associated with Multifocal Intracranial and Extracranial Aneurysms: Case Report and Literature Review

Peripheral ophthalmic artery aneurysm is a rare disease entity. We review the relevant literature and report a case of fusiform aneurysm involving the entire intraorbital ophthalmic artery in association with multiple intracranial and extracranial aneurysms, diagnosed on digital subtraction angiography. The patient suffered irreversible blindness secondary to compressive optic neuropathy which did not improve after a 3-day trial of intravenous methylprednisolone. Autoimmune screen was normal. The underlying cause is unknown.
