Three patients with Sturge-Weber syndrome (5 months, 6 years, and 17 years old) were studied prospectively with MR imaging and CT of the brain. Both techniques demonstrated parenchymal volume loss, choroid plexus enlargement, calvarial hemiatrophy, and proptosis. In regions of parenchymal volume loss, MR alone demonstrated thickened cortex with decreased convolutions and abnormal white matter. A focal thalamic lesion and prominent medullary and subependymal veins were also shown better by MR. However, CT definitively demonstrated the characteristic cortical calcification, while T2-weighted MR images detected only smaller, nonspecific foci of hypointense signal. MR and CT are complementary in the evaluation of Sturge-Weber syndrome.
对3例患有斯特奇-韦伯综合征的患者（年龄分别为5个月、6岁和17岁）进行了脑部磁共振成像（MR）和计算机断层扫描（CT）的前瞻性研究。两种技术均显示脑实质体积减小、脉络丛增大、颅骨半侧萎缩和眼球突出。在脑实质体积减小的区域，仅MR显示皮质增厚、脑回减少和白质异常。MR还能更好地显示局灶性丘脑病变以及显著的髓质和室管膜下静脉。然而，CT能明确显示特征性的皮质钙化，而T2加权MR图像仅检测到较小的、非特异性的低信号灶。在斯特奇-韦伯综合征的评估中，MR和CT具有互补性。
