脑海绵状血管瘤的影像表现

Image Appearances of Cerebral Cavernous Angioma

目的 探讨脑海绵状血管瘤的影像表现。方法 脑海绵状血管瘤58例全都作MRI检查,其25例曾作DSA和48例曾作CT检查。分析脑海绵状血管瘤的影像表现。结果 脑海绵状血管瘤DSA常呈阴性,CT的敏感性和特异性有欠缺,而MRI有较高的敏感性和特异性。结论 MRI对脑海绵状血管瘤有重要的临床诊断价值。

Objective To probe into the image appearances of the cerebral cavernous angioma (CCA). Methods All the 58 patients with CCA, of them, 25 were examined by DSA and 48 by CT, were examined by MRI. The imaging data of the 58 patients with CCA were analysed. Results The appearances of CCA on DSA often was negative. The sensitive and specificity of CCA appearances on MRI, but not CT were satisfactory for diagnosing it. Conclusion MRI has an important diagnostic value in the patients with CCA.
