The basilar artery as the origin of the ophthalmic artery is extremely rare. A 48-year-old patient had undergone angiography for suspicion of a right middle cerebral artery aneurysm. No aneurysm was detected. Vertebral artery injections demonstrated the left ophthalmic artery originating from the basilar trunk. Current embryologic theories fall short in explaining this entity. Awareness of neuroanatomic variations is of paramount importance in diagnosis and treatment of vascular lesions of the brain.
以基底动脉作为眼动脉起源极为罕见。一名48岁患者因怀疑右侧大脑中动脉动脉瘤接受了血管造影检查。未检测到动脉瘤。椎动脉造影显示左眼动脉起源于基底动脉干。目前的胚胎学理论无法解释这一现象。认识神经解剖变异对于脑部血管病变的诊断和治疗至关重要。
