| 中文摘要: |
| 目的：研究脑发育性静脉畸形（Cerebral Developmental Venous Anomalies，CDVA）临床及影像学特征及复习CDVA 文献。
方法：回顾性收集了自2011 年11 月至2014 年3 月我科确诊的9 例CDVA的病人，对其临床特征、影像学检查方法包括电子计
算机断层扫描（Computed Tomography，CT）、核磁共振成像（Magnetic Resonance Imaging，MRI）、数字减影血管造影（Digital
Subtraction Angiography，DSA）及特征进行分析并对相关文献进行复习。结果：（1）临床症状：9 例病人的临床症状包括头晕4例
（4/9）、头痛4 例（4/9）、恶心不适2 例（2/9）、站立不稳1 例（（1/9）、小脑出血史1 例（1/9）、眼部症状行眼科检查偶然发现小脑
CDVA1 例（1/9）；（2）病变部位：病变位于幕上4 例（4/9）；幕下5 例（5/9）；（3）影像学检查：9 例病人中，6 例行CT 平扫或增强扫描
（3例平扫，3 例平扫+增强）；4 例行MRI（1 例平扫，3 例平扫+增强）；3 例行DSA 检查；（4）影像学特点：CT 增强及重建、MRI的
T1WI增强、SWI、MRA及DSA静脉期像均可显示出髓静脉及其形成的特征性“海蛇头”征象和其引流静脉。结论：CT、MRI、DSA
影像学方法均可用于CDVA的诊断，在临床实践中需根据需要优化选择联合应用。 |
| 英文摘要: |
| Objective:To study the clinical and imaging features of cerebral developmental venous anomalies (CDVA) and
review the literatures.Methods:Nine cases of CDVA were retrospectively collected from November, 2011 to March, 2014. The clinical
features and imaging examination including computed tomography (CT), magnetic resonance imaging (MRI), and digital subtraction
angiography (DSA) were analyzed and the related literatures were reviewed.Results:(1) Symptoms: Of 9 cases, 4 cases with dizzy(4/9),
4 cases with headache(4/9), 2 cases with nausea(2/9), 1 case with astasia(1/9), 1 case with history of cerebellum hemorrhage, 1 case with
fortuitous findings by ophthalmologic examination (1/9); (2) Location: Of 9 cases, 4 cases with supratentorial lesion (4/9), 5 cases with
infratentorial lesion(5/9); (3) Images modalities: Of 9 cases, 6 cases with CT scan or contrast-enhancement CT( of these, 3 cases with CT
scan, 3 cases with CT scan+contrast-enhancement), 4 cases with MRI ( of these, 1 case with non-contrast MRI, 3 cases with non-contrast
and contrast-enhancement MRI), 3 cases with DSA; (4) Imaging features: The dilated medullary veins (forming a typical caput medusae
sign) and collector veins can be showed no matter contrast-enhancement CT and reconstruction techniques, contrast-enhancement MRI
and SWI image or venous phase DSA.Conclusion:The imaging modalities including CT, MRI and DSA can be employed for the
diagnosis of CDVA. But, the combination and optimal choice of these modalities for different cases is important to clinical practice. |
