Hyperostosis of the sphenoid ridge or convexity of the skull associated with meningioma en plaque (MEP) is often confused with other hyperostosing conditions, such as fibrous dysplasia or osteoma. The authors present nine cases, six of them proven, of hyperostosing MEP with specific attention to the CT features. All nine cases had one or more CT features that were characteristic or suggestive of MEP. These included periosteal pattern of hyperostosis, inward bulging of the vault lesion, surface irregularity of the hyperostotic bone, and intracranial changes. The role of CT in evaluating MEP is compared with other neuroradiologic techniques. The results indicate that high-resolution CT is the neuroimaging method of choice in evaluating MEP.
蝶骨嵴骨质增生或颅骨凸面骨质增生伴扁平状脑膜瘤（MEP）常与其他骨质增生性疾病相混淆，如骨纤维异常增殖症或骨瘤。作者报告了9例骨质增生性MEP病例，其中6例已得到证实，并特别关注了其CT特征。所有9例病例均具有一个或多个具有MEP特征性或提示性的CT表现。这些表现包括骨膜下骨质增生模式、颅骨病变向内膨隆、骨质增生部位的表面不规则以及颅内改变。将CT在评估MEP中的作用与其他神经放射学技术进行了比较。结果表明，高分辨率CT是评估MEP的首选神经影像学方法。
