Although many cerebral vascular anomalies are widely recognized, others are less well known or unclassified. Accessory middle cerebral artery (MCA) and duplicated MCA are among uncommon anomalies. We present a very rare case of subarachnoid haemorrhage due to rupture of a saccular aneurysm arising from a duplicated middle cerebral artery which was associated with an accessory middle cerebral artery.
尽管许多脑血管异常已广为人知，但其他一些则鲜为人知或未被分类。副大脑中动脉（MCA）和大脑中动脉重复畸形属于罕见的异常情况。我们报告了一例非常罕见的蛛网膜下腔出血病例，其病因是起源于大脑中动脉重复畸形且伴有副大脑中动脉的囊状动脉瘤破裂。
