Abstract

BACKGROUND: Anterior ethmoid aneurysms are rare with 5 cases of intracranial rupture and 3 cases of life-threatening epistaxis described in recent literature. We present a case of an intracranial ruptured anterior ethmoid aneurysm treated surgically with a favorable outcome.

CASE DESCRIPTION: A 64-year-old male presenting with a headache was found to have a right frontal intracranial hemorrhage with an associated 1.5 cm length × 1.8 cm maximal width anterior ethmoidal artery aneurysm. No definitive etiology of the aneurysm was identified. The aneurysm was treated using a bifrontal craniotomy with interhemispheric microdissection, clip ligation, and resection of the aneurysm dome for pathologic analysis, which ruled out a mycotic etiology. He recovered uneventfully and returned to work with no identifiable neurologic deficit.

CONCLUSIONS: Consistent with prior reports, an intracranial, anterior ethmoidal artery aneurysm can occur in isolation without an associated vascular malformation. On the basis of a literature review and this case, surgical ligation is considered effective and possibly superior over endovascular treatment due to the risk of injury to the orbital vascular supply with transarterial treatment.
