颅内海绵状血管瘤的MRI诊断

MRI Diagnosis of Intracranial Cavernous Angiomas

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 T 1 weighted image showed equal or high signal intensity, T 2 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. [
