【摘要】 目的　探讨脑内海绵状血管瘤(CA)的影像学表现并评价其临床意义。方法　搜集经手术病理证实的脑内海绵状血管瘤21例,21例均行CT检查,16例行MRI检查。结果　CT发现22个病灶,MRI发现23个病灶,多发者5例,病灶位于皮层及皮层下区共18个。16个病灶具有典型脑内型CA的MRI表现,即由低信号环围绕的混杂信号团块。结论　MRI是脑内型CA最佳检查方法,且具有重要的临床意义。更多还原

【Abstract】 Objective To study and eveluate CT and MRI imaging finding of intra axial cavernous angioma. Methods 21 cases of intra axial cavernous angioma with pathologic were studied. 21 cases all had CT scan, 16 cases had MRI scan. Results 22 lesions were finded by CT, and 23 lesions by MRI. 5 cases were multifocal, 18 lesions were located at cortex and cortricomedullary junciton. 16 lesions showed a typical popcorn-like mixed signals with hypointensity ring on MRI. Conclusion MRI was the most useful method for diagosis of intra axial cavernous angioma, and has an important clinical signification. [更多还原
