Arteriovenous malformation (AVM) combined with aneurysms is not uncommon, but AVM of the basilar artery, brainstem, and right middle cerebral artery combined with multiple intracranial aneurysms (IAs) is rare. Cases of aneurysm protrusion into the optic canal are also rare. We report a distinctive case of intracranial AVM combined with multiple IAs and partial protrusion of a cavernous segment aneurysm of the right internal carotid artery into the optic nerve canal.
Cases of partial protrusion of a cavernous segment aneurysm of the right internal carotid artery into the optic canal, resulting in widening of the optic canal compared to the contralateral side, compression, thickening and swelling of the subocular veins, and obstruction of venous drainage warrant the clinician's attention.
动静脉畸形（AVM）合并动脉瘤并不少见，但基底动脉、脑干及右侧大脑中动脉的AVM合并多个颅内动脉瘤（IA）则较为罕见。动脉瘤突入视神经管的病例也很罕见。我们报告了一例独特的颅内AVM合并多个IA，以及右侧颈内动脉海绵窦段动脉瘤部分突入视神经管的病例。
右侧颈内动脉海绵窦段动脉瘤部分突入视神经管，导致患侧视神经管较对侧增宽、眼静脉受压、增粗及肿胀，以及静脉引流受阻，这种情况值得临床医生关注。
