·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.·
