摘要
目的:分析桥小脑角区表皮样囊肿的M R I表现并对其生长和蔓延方式分型。方法:收集我院经手术病理证实的表皮样囊肿11例,男6例,女5例,行M R检查。结果:本组病例中,绝大多数表皮样囊肿呈高于脑脊液、低于脑实质信号的均质性肿瘤,生长和蔓延方式多样。结论:桥小脑角区表皮样囊肿的M R I表现具有特征性,并可根据M R I表现进行分型诊断。
Objective To analyze MRI features of epidermoid tumor of the cerebellopontine angle area and determine its growth and extended type. Methods Eleven patients （6 male, 5 female） with histologically proven epidermoid tumor of the cerebellopontine angle area were studied with MR equipment. Results The tumors showed homogeneous signal intensity which was higher than CSF and lower than brain parenchyma, and the tumors had various kinds of growth and extended type. Conclusion Epidermoid tumor of the cerebellopontine angle area has characteristic MRI features, and could be determined its growth and extended type according to the MRI appearance.
