目的 :利用现代影像检查手段 ,对眼眶皮样囊肿的定位及定性诊断进行分析比较。方法 :对2 5例眼眶皮样囊肿的X线、B超、彩色超声多普勒、CT、MRI检查结果进行观察分析。结果 :X线检查能粗略反映眼眶骨骼改变。超声多普勒反映肿瘤的血流情况。B超、CT、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结构和动态 ,CT确定空间位置较精确。MRI上信号高低与脂质、H+含量有关。T1WI像上有高信号。结论 :上述影像检查均对眼眶皮样囊肿诊断有帮助 ,CT检查最有价值。超声或MRI与CT检查相结合 ,能得出最佳定性、定位诊断
OBJECTIVE: To analyze and compare the localization and qualitative diagnosis of orbital dermoid cysts with modern imaging methods. Methods: The results of X-ray, B-mode ultrasonography, color Doppler ultrasound, CT and MRI in 25 orbital dermoid cysts were observed and analyzed. Results: X-ray examination can roughly reflect the orbital bone changes. Doppler ultrasound reflects the tumor’s blood flow. B ultrasound, CT, MRI can determine the location of the lesion and prompt the nature of the lesion, but the B-ultrasound can better show the structure and dynamics within the lesion, CT to determine the spatial location more accurate. MRI signal level and lipid, H + content. There is a high signal on the T1WI image. Conclusion: The above imaging examination is helpful for the diagnosis of orbital dermoid cyst. CT examination is the most valuable. Ultrasound or MRI and CT combined to obtain the best qualitative diagnosis of positioning
