摘　　要：目的探讨脑静脉性血管畸形相邻脑实质异常的MRI表现及相关因素。方法对36例静脉性血管畸形患者的影像资料进行回顾性研究，分析其引流区域脑实质异常的发生率及MRI表现，分析其与性别、年龄及发病部位的关系。结果静脉性血管畸形相邻脑实质异常的发生率为50％（18／36），表现为伴发海绵状血管瘤（8例）或静脉畸形引流区域的信号异常，包括白质病变（4例）、出血（4例）和钙化（2例）。静脉性血管畸形有与无相邻脑实质异常患者在年龄、性别及病变部位上的差别无统计学显著意义，但静脉畸形同一部位伴发海绵状血管瘤的患者有多见于中年女性的趋势。结论MRI可以明确显示静脉性血管畸形引流区域脑实质异常，其病因尚不明确，可能与局部血流动力学的改变有关。Objective To evaluate the MR manifestations of parenchymal abnormalities associated with cerebral venous malforma- tion[CVM） and the correlation factors. Methods Imaging data of 36 patients with CVM were analyzed retrospectively. The preva lence of parenchymal abnormalities associated with CVM and their MR manifestations were assessed. The relationship between pa- renchymal abnormalities and gender, age and location were analyzed. Results The prevalence of parenchymal abnormalities associ- ated with CVM was 18/36{50 %）. The parenchymal abnormalities included cavernous angiomas in association with CVM （8 cases）, and signal-intensity abnormalities within the drainage territory of CVM, i. e, white matter signal alternations { 4 cases）, presence of haemorrhage {4 cases） and calcifications {2 cases）. There was no significant difference in gender, age and location between patients with parenchymal abnormalities and those without abnormalities. But the cavernous angiomas in association with CVM had a tenden- cy to occur in middl^aged female. Conclusion MRI can reveal the parenchymal abnormalities associated with CVM. The etiology is unclear, and may be related to the altered hemodynamics.
