| 摘 要： | 目的 分析颅内表皮样囊肿的MRI影像学表现。方法 证实的 18例患者中 ,男 7例 ,女 11例 ,全部行MRI检查。结果 典型表现者 16例 ,占 88.9% ,T1WI表现为低信号 ,T2 WI表现为高信号 ;不典型表现者 2例 ,占 11.1% ,T1WI表现为欠均匀高信号 ,T2 WI表现为高信号。增强扫描 ,16例肿瘤不强化 ,2例边缘强化。结论 典型表皮样囊肿是T1WI呈低信号 ,且欠均质 ;非典型表皮样囊肿T1WI呈高信号 ,应注意此类肿瘤的鉴别诊断。

| Abstract: | Objective To study the MR imaging features of intracranial epidermal cyst.Methods 18 cases(include 7 male,11 female) epidermal cyst pathology confirmed were analysed.Results The epidermal cyst usually exhibited heterogeneously low signal intensity on T 1WI(88.9%),and only 2 patients showed high signal intensity on T 1WI(11.1%).After contrast medium enhancement 16 cases had no obvious enhancement,only 2 patients had rim light enhancement .Conclusion Typical epidermal cyst commonly show heterogenously low signal intensity on T 1WI. A typcal epidermal cyst has high signal intensity on T 1WI.Differential diagnosis shoud be consider on these kind of epidermal cyst. |
