目的：作者报告2例肥厚性硬脑（脊）膜炎，并结合文献对其影像学表现进行分析。材料与方法：采用CT（SCT4500TE）平扫和增强，MRI（ASM0．15P，0．15T）平扫和增强，造影剂为非离子型造影剂和Gd－DTPA顺磁性造影剂，结果：CT所见沿颅板下弥漫性硬脑膜增厚，增强后增厚硬脑膜明显强化，依部位不同可有不同的占位效应。MRI表现为T；W脊髓变细，蛛网膜腔增定，T2W脊髓弥漫性高信号，蛛网膜腔变窄，增强育髓周围硬脑膜明显强化。结论：作者认为CT、MRI检查对肥厚性硬脑、脊膜炎有较高的敏感性和特征性表现，有利于早期诊断和治疗。
OBJECTIVE: The authors report 2 cases of hypertrophic dural (spinal) meningitis and analyze the imaging findings based on the literature. Materials and Methods: CT scan and contrast enhancement (SCT4500TE), MRI (ASM0.15P, 0.15T) scan and contrast enhancement were performed. Contrast media were nonionic contrast media and Gd-DTPA paramagnetic contrast media. Results: See diffuse dura along the thickening of the skull, thickening and thickening of the dura markedly enhanced, depending on the site may have different placeholder effect. MRI showed T; W spinal cord thinning, arachnoid buildup, T2W spinal cord diffuse high signal, narrowing of the arachnoid cavity, enhance the dura mater significantly enhanced around the spinal cord. Conclusion: The authors believe that CT, MRI examination of hypertrophic sclera, meningitis has a high sensitivity and characteristic performance, is conducive to early diagnosis and treatment.
