| 中文摘要: |
| 目的探讨颅内海绵状血管瘤(CA)MRI表现。方法对5年来我院收治的19例CA的MRI表现进行分析,男9例,女10例,年龄31～72岁,其中30～40岁的有12例。结果19例发现病灶25个,6个在T1WI上呈等信号,19个为高信号,在T2WI上全部病灶为高信号,其中9个病灶周围伴有环形低信号,大多数病灶较小,周围无水肿带,无占位效应。 |

| Purpose To study MR imaging manifcstation of intracranial cavernous angiomas.Methods Retrospective analysis of 19 cases of CA treated in the last 5 years.19 patients with CA (male 9,female 10) were studied, age ranged from 31 to 72 years, among with, 12 cases were ranged from 30 to 40 years.Results The lesions on T1 weighted image showed equal or high signal intensity, T2 weighted image showed high signal intensity, and the “ring” sign of low signal around CA could be seen in some cases. The lesions of CA mostly were small and there were no mass effect or edema around them. Conclusion MR examination was the most sensitive method for diagnosis of CA. |
