摘　　要：目的讨论磁共振扩散成像诊断颅内表皮样囊肿的有用性和特异性。方法收集我院经手术病理证实的表皮样囊肿患者25例,其中,男11例,女14例,行MRI检查。结果磁共振扩散成像显示所有肿瘤(25个瘤灶)呈明亮的高信号,肿瘤与周围脑组织和脑脊液形成鲜明的对比。结论磁共振扩散成像对鉴别表皮样囊肿有较高的应用价值。Objective To discuss the usefulness and specificity of MR diffusion weighted imaging （DWI） in the diagnosis of intracranial epidermoid cyst. Methods Conducted MRI examination to 25 cases （17 males and 19 females） of epidermoid tumor which were diagnosed by surgical pathology. Results DWI shows that all tumors （n=25） have bright high signal, and form strong contrast with cerebrospinal fluid （CSF） and brain tissues around. Conclusion DWI has higher application value in diagnosis of intracranial epidermoid cyst.
