摘要
目的 探讨脉络丛乳头状瘤(choroid plexus papilloma,CPP)的MR表现及临床意义。方法 回顾性分析11例脑室内CPP的MR表现。结果 4例(36.3%)位于第四脑室,7例(63.7%)位于侧脑室,瘤体均呈分叶状或菜花状,边缘凹凸不平,边界清晰,T1WI呈等或稍低信号,T2WI信号混杂,T2FLAIR呈高信号,DWI病灶呈低信号,增强明显强化,瘤体内可见结节状、细小颗粒状低强化区,10例(90.9%)合并脑积水。结论 脑室内CPP的MR表现有一定的特征,MR对于病灶内部信号,周围结构能清晰显示,给予临床的治疗提供更多有用信息。
Objective To investigate the MR findings and clinical significance of choroid plexus papilloma(CPP). Methods Retrospective analysis of MR findings in 11 cases of ventricular CPP. Results 4 cases(36.3%)were located in the fourth ventricle,and 7 cases(63.7%)were located in the lateral ventricle,the tumors were lobulated or cauliflower-like,with uneven edges and clear boundaries,T1WI showed equal or slightly hypointensity,T2WI signal was mixed,T2FLAIR showed hyperintensity,and DWI lesion showed hypointensity,the enhancement was obviously enhanced,and nodular,fine granular low-enhancement areas could be seen in the tumor,10 cases(90.9%)with hydrocephalus. Conclusion The MR manifestations of intracranial CPP have certain characteristics,MR for the internal signal of the lesion,the surrounding structure can be clearly displayed,providing more useful information for clinical treatment.
