Clinical Case Notes

Abstract

Angiographically documented aneurysms of the intraorbital ophthalmic artery are extremely rare. Two cases are presented of intra­orbital ophthalmic artery aneurysms, both associated with arteriovenous malformation (AVM). There have only been isolated reports documenting this combination of vascular anomalies. In the first case, the aneurysm was treated conservatively and in the second case, after staging angiography and interventional embolization, the aneurysm was removed along with the associated AVM. The clinical presentation, pathogenesis and management of this rare combination of vascular anomalies is briefly discussed.

Intraorbital False (Thrombosed) Aneurysm of the Meningolacrimal Branch of the Middle Meningeal Artery: A Case Report and an Appraisal of Anatomy

“…[1][2][3][4][5] To the best of our knowledge, the ophthalmic artery is the only reported source of aneurysms within the orbit.…”

Spontaneous Intraorbital Hemorrhage : A Case Report

“…It may occur in patients with intraorbital arteriovenous malformation, cavernous angioma, or aneurysms of the intraorbital ophthalmic artery, aneurysms of the ophthalmic vein, and orbital pseudotumor, or other inflammatory disease 5,8,9,10,11,12,15) . The symptoms occur abruptly or gradually and diagnosis is made by cerebral angiography in addition to orbital computed tomography and MRI.…”

“…It may occur in patients with various vascular abnormalities such as intraorbital arteriovenous malformation, cavernous angioma, or aneurysms of the intraorbital ophthalmic artery, aneurysms of the ophthalmic vein 6,8,10,12,15) . Also, it may occur in association with neoplasms or idiopathic inflammatory orbital pseudotumor 5,9,11,13) .…”

“…Also, it may occur in association with neoplasms or idiopathic inflammatory orbital pseudotumor 5,9,11,13) . Intraorbital hemorrhage with vascular anomalies present with sudden or gradual onset of severe ophthalmic pain, exophthalmos, decreased visual acuity, diplopia, etc 6,8,10,12,15) . Orbital pseudotumor with hemorrhage and spontaneous intraorbital hemorrhage without any causes was reported in very rare occasions.…”

Vascular Malformations of the Orbit

“…35,36 Arterial Dysplasias. Arterial aneurysms are rare in the orbit and are usually nonsymptomatic but may require intervention.…”
