Cerebral arteriovenous malformation (AVM) is a common type of cerebral vascular malformation. The imaging findings are enlarged vessels, thrombosed sinuses, and hemorrhage or gliosis on adjacent brain parenchyma. Magnetic resonance (MR) imaging can be used safely for diagnosis. Chiari type I malformation is characterized by a caudal descent of the cerebellar tonsil. Coincidence of cerebral AVM and Chiari type I malformation is very rare. In this paper, the authors report MR imaging findings of a patient with coincidence of cerebral AVM and Chiari type I malformation.
脑动静脉畸形（AVM）是一种常见的脑血管畸形类型。影像学表现为血管增粗、静脉窦血栓形成以及相邻脑实质内的出血或胶质增生。磁共振（MR）成像可安全用于诊断。Chiari I型畸形的特征是小脑扁桃体尾端下移。脑AVM与Chiari I型畸形同时存在的情况非常罕见。在本文中，作者报告了一例脑AVM与Chiari I型畸形同时存在患者的MR成像表现。
