眼眶横纹肌肉瘤的彩色多普勒超声检查

Color Doppler ultrasonography examination in orbital rhabdomyosarcoma

目的:总结分析眼眶横纹肌肉瘤的临床表现及彩色多普勒超声表现,为临床诊断及治疗提供参考。方法:对我科1996-01/2009-12诊治的16例眼眶横纹肌肉瘤患者的彩色多普勒超声表现进行回顾性分析。从肿物位置、形状,内回声以及血流分布、形状、动力学参数方面进行总结,归纳眼眶横纹肌肉瘤的彩色多普勒超声特点结果:病变多位于眼眶上部,呈类圆形或不规则形,内回声为中或低回声,多不均匀,声衰减不明显。血流信号较多,星点状,血流频谱为动脉频谱。结论:彩色多普勒超声具有操作简便、无创、动态下观察、显示病变内血流分布及频谱等特点,可以了解病变内血流供应,对于眼眶横纹肌肉瘤的诊断和治疗具有指导意义。

AIM： To analyse the clinical and color Doppler ultrasonography imageological characters of orbital rhabdomyosarcoma for the sake of clinical diagnosis and management. METHODS： Sixteen cases of orbital rhabdomyosarcoma from Jan. 1996 to Dec. 2009 were reviewed as a retrospective study. The tumor location,shape,internal echo, distribution,shape and kinetic parameter of blood flow were summed up accordingly, rhabdomyosarcoma in color doppler ultrasonography was summarized. RESULTS： Multiple lesions were in the upper part of the orbit, showing round or irregular in shape, internal echo was medium or low and most was not uniform, sound attenuation was not obvious.Blood flow showed more signal, star or dot in shape, and arterial spectrum. CONCLUSION： Color Doppler ultrasonography is simple, non-invasive with dynamic observation, indicating lesions in blood flow distribution and characteristics of the spectrum for us to understand the blood supply. Color Doppler ultrasonography is extraordinarily helpful in the diagnosis and management of orbital rhabdomyosar-coma.
