MRI Diagnosis of Choroid Plexus Papilloma(with 10 cases reports)

目的分析脉络丛乳头状瘤的MRI表现,旨在提高对本病的诊断水平。方法回顾性分析10例经手术及病理证实的脉络丛乳头状瘤的MRI表现。结果多数肿瘤呈实性(9/10);T1WI呈等低信号、T2WI呈等高信号、FLAIR呈略高信号,增强后大部分肿瘤明显强化(9/10)。肿瘤边缘呈乳头状或分叶状;肿瘤多位于四脑室(7/10),少数肿瘤位于侧脑室(3/10)。10例肿瘤均引起脑积水。结论脉络丛乳头状瘤的MRI表现具有明显特征性,仔细观察能提高其术前诊断正确率。

Objective Analysis the？MRl findings of？choroid plexus papilloma, Andto improve thediagnosis？ level. Methods A etrospective analysis of MRI findings in I0 cases choroid plexus papilloma confirmed by surgery and pathology. Results Most tumors were solid （9/I0）, TIWI showed low-signal, T2WI showed high-signal, while FLAIR was slightly higher signal. Most of the tumor was significantly enhanced （9/10）. The tumor edges were papillary or lobulated, Most tumors located in the fourth ventricle （7/10）, when a small number of tumors located in the lateral ventricle （3/I0）. Hydrocephalus were caused by all the 10 cases tumors. Conclusion MRI findings of choroid plexus papilloma has distinct characteristics, It can improve the preoperative？diagnostic accuracy when you observe carefully.
