摘要
目的 联合应用超声、CT、MRI对眼眶皮样囊肿进行检查 ,并对比分析 ,以术前得出正确诊断。方法 利用15年期间诊治的眼眶皮样囊肿 12 5例做回顾性分析 ,对比各种检查结果的特征。结果 B型超声、彩色多普勒超声、CT、MRI均可发现病变。超声检查可以确定病变的声学性质和内部血流情况 ;CT能够准确定位 ,并且在揭示继发改变 ,如骨增生、骨缺失等方面优于超声 ;MRI可清楚地显示肿物颅内或颞窝蔓延。结论 联合应用超声、CT及MRI多种检查方法 。
ObjectiveTo observe the iconologic characteristics of dermoid cysts and evaluate the diagnostic value of ultrasonography, CT and MRI. Method125 cases with orbital dermoid cysts were analysed. Results of different examination were compared. ResultsLesions can be found by B scan, color doppler imaging, CT and MRI. Ultrasonography could determine the acoustic character and blood distribution of lesions. CT could locate lesions correctly and showed secondary changes, such as bone proliferation and bone defect. MRI displayed intracranial and temporal extention of lesions. ConclusionComprehensive examination can reveal whole characters about dermoid cysts.
