颅内海绵状血管瘤的CT、MRI与DSA对比研究

A comparative study of CT,MRI and DSA in diagnosis of intracranial cavernous angioma

目的 :探讨CT、MRI、DSA对颅内海绵状血管瘤的诊断价值。方法 :经手术病理证实的颅内海绵状血管瘤2 7例 (脑内型 2 2例 ,脑外型 5例 ) ,其中 9例行CT扫描 ,2 4例行MRI检查 ,10例行DSA检查 ,分别分析其影像学表现。结果 :颅内海绵状血管瘤的CT表现为稍高密度影 ,MRI表现为混杂信号团块 ,DSA检查未见异常染色。结论 :颅内海绵状血管瘤的MRI表现比较有特异性 ,综合CT、MRI和DSA所见有利于正确的诊断。

Objective:To investigate the diagnostic value of CT,MRI and DSA in diagnosis of intracranial cavernous angioma.Methods:27 cases of intracranial cavernous angioma,including 22 cases of intra axial lesions,and 5 of extracerebral lesions,were proved by surgical and pathologic findings.9 of them were performed CT,24 performed MRI,and 3 performed DSA.Results:Intracranial cavernous angioma appeared slight hyperdense on CT,heterogeneous intense on MRI,and negative on DSA.Conclusion:Intracranial cavernous angioma is of specific feature on MRI.The combination of CT,MRI and DSA is helpful for the diagnosis of the disease.
