肥厚性硬脑,脊膜炎的影像诊断

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。

Imaging Diagnosis of Hypertrophic Craniospinal Pachymenigitis

Purpose: The imaging menifestations of 2 cases of hypertrophic craniospinal pachymenigitis were analysed and relative literature was reviewed. Materials and Metbods: The patient were examed with conventional and enhanced CT scan,MRI. Non-ionic agents and paramagnetic contrast media were used respectively. Results: CT image shows extensive thicking and enhancement of dura' There were different features of mass effect acconding to the different place' Spinal cord thin and subarachnoid space widen on T, -weighted image. Diffuse high signal of spinal cord was found and subarachnoid space narrow on T2 -weighted image, dura around spinal cord was enhanced greatly. Conclusiou: There are higher sensitivity and charaiteristic findings of hypertrophic craniospinal pachymenigitis on CT scan, MRI examination. It makes possibility in the earlier diagnosis and therapyof the disease.
