A 21-year-old male presented with visual disturbance followed by severe headache. Computed tomography showed right thalamic hemorrhage entering the right lateral ventricle. Cerebral angiography revealed bilateral symmetrical arteriovenous malformations (AVMs) fed by the lenticulostriate, anterior choroidal, and lateral posterior choroidal arteries and draining into the vein of Galen. Partial removal of the right AVM induced bleeding on the left side, probably due to postoperative hemodynamic changes. Bilateral symmetrical cerebral AVMs are extremely rare, but provide serious problems for surgical intervention in the deep cerebrum.
一名21岁男性出现视力障碍，随后出现严重头痛。计算机断层扫描显示右侧丘脑出血破入右侧侧脑室。脑血管造影显示双侧对称性动静脉畸形（AVM），由豆纹动脉、脉络膜前动脉和脉络膜后外侧动脉供血，并引流至大脑大静脉。右侧AVM部分切除后左侧出血，可能是由于术后血流动力学改变所致。双侧对称性脑AVM极其罕见，但给深部大脑的手术干预带来严重问题。
