摘　　要：目的 :比较分析影像检查方法对眼眶皮样囊肿的定位及定性诊断的价值。方法 :对 2 1例眼眶皮样囊肿的B超、CT扫描及磁共振成像 (MRI)检查结果进行观察分析。结果 :B超、CT和MRI均可确定病变位置并提示病变的性质 ,但B超能较好显示病变内部结构和动态 ,CT发现病变及确定位置较精确 ,MRI特征为T1WI、T2 WI均为高信号。结论 :3种影像检查中 ,CT检查对眼眶皮样囊肿最有价值 ,3种手段相结合能得出最佳定性、定位诊断。Objective To compare and analyze the modern photographic methods used for locatization and analysis of the nature of orbital dermoid cysts.Methods B scan,CT scan and magnetic resonance imaging (MRI)were used to examine 21 cases of orbital dermoid cyst. The imagings were analyzed.Results Each of B scan,CT scan and MRI can locate and show the mature of the lesions. B scan has a better value to display internal structure and dynamics of the lesions. CT can discover the lesions and exactly show their locations. The result of MRI examining was connected with sebum and H +. Conclusions All the above methods can give help to locate and show the nature of orbital dermoid cysts. CT scan is the most important examining. The most valuable diagnosis in localization and showing nature can be got thoughout combining B scan and MRI with CT.
