Report on the rare case of a ruptured pericallosal aneurysm originating from an atypic communicating segment between both distal A2 arteries, called the 'supreme anterior communicating artery'. The neurosurgeon should be aware of this rare vascular anomaly that might be angiographically occult and raise unexpected intraoperative difficulties.
关于一例罕见的胼周动脉瘤破裂的报告，该动脉瘤起源于双侧大脑前动脉A2段远端之间的非典型交通段，即所谓的“最高前交通动脉”。神经外科医生应了解这种罕见的血管异常情况，其在血管造影上可能隐匿，并可能引发意想不到的术中困难。
