颅内自发皮样囊肿破裂的MRI诊断

摘要

目的 探讨颅内皮样囊肿破裂(intracranial dermoid cyst)的特殊影像表现,提高影像诊断准确性.资料与方法回顾性分析颅内皮样囊肿破裂患者的平扫及Gd-DTPA增强扫描资料.结果 颅内中线旁含脂样成分囊性病变.结论 MRI具有多方位、多参数、多序列成像,软组织分辨率高的优点,对颅内皮样囊肿诊断的准确率高,简便易行.%Objective To discuss the special imaging finding of intracranial dermoid eyst,thus to enhance the imaging diagnois accuracy.Meterials and Methods Retrospectively analyed the plain scan and the Gd-DTPA contrast enhancement data for the patient of ruptured intracranial demoid cyst. Results Nearby the encephalic median line contains the fat trpe ingredient cystic pathological change. Conclusion MR can be provide with the advantage of multi-positions,multi-parameters,multi-sequence imaging,high resolution of soft tissue and so on.The diagnosis for the intracranial dermoid cyst is much accurate and convenient.
