Abstract

The developmental anomaly of the middle cerebral artery (MCA) is a rare occurrence. Rete MCA, also known as "unfused," "twig-like," and aplastic MCA, is an even rarer anomaly. These immature rete vessels are prone to flow-related aneurysms which rupture themselves presenting with intraparenchymal hematoma. We here with present a case of rete MCA with a ruptured aneurysm and discuss its pathophysiology and management.

摘要

大脑中动脉（MCA）发育异常较为罕见。大脑中动脉吻合支（MCA），又称“未融合”、“树枝状”和“发育不良 MCA”，则更为罕见。这些不成熟的吻合血管容易发生与血流相关的动脉瘤，进而破裂导致脑实质血肿。我们在此报告一例大脑中动脉吻合支破裂的动脉瘤病例，并讨论其病理生理学和处理方法。
