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。结论ＭＲ是诊断ＣＡ最敏感的方法 Objective To investigate the MRI findings of intracranial cavernous hemangioma (CA). Methods The MRI findings of 19 cases of CA treated in our hospital during 5 years were analyzed. There were 9 males and 10 females, ranging in age from 31 to 72 years, of whom 12 were from 30 to 40 years old. Results Twenty-five lesions were found in 19 cases. Six of them showed equal signal on T1WI and 19 were high signal. All lesions were high signal on T2WI. Nine lesions were accompanied by a ring-shaped low signal, most lesions were smaller. No edema, no placeholder effect. Conclusion MR is the most sensitive method for the diagnosis of CA.
