目的探讨颅内脑外海绵状血管瘤的MRI表现和诊断价值。方法回顾性分析经手术病理证实颅内脑外海绵状血管瘤15例的MRI表现。结果病灶均位于中颅窝和鞍旁,MRI呈圆形或类似哑铃形肿块,较均匀的稍长T1、长T2信号,增强扫描一般见明显均匀强化。结论颅内脑外型海绵状血管瘤的MRI表现较有特异性,结合临床资料和影像学征象的综合分析可以诊断。
Objective To investigate the MRI findings and diagnostic value of intracranial cavernous hemangiomas. Methods Retrospective analysis of 15 cases of intracranial cavernous hemangiomas confirmed by surgery and pathology. Results The lesions were located in the middle cranial fossa and the parasellar. The MRI showed a round or similar dumbbell-shaped mass. Compared with the slightly longer T1 and T2 signals, the lesions showed generally uniform enhancement. Conclusion The intracranial brain cavernous hemangioma has more specific MRI findings. Combined with clinical data and imaging findings, it can be diagnosed.
