Abstract:
Objective To evaluate the value of ultrasound in the diagnosis of benign and malignant ovarian teratomas.Methods The ultrasonographic imaging features of eighty-four cases of benign and malignant ovarian teratomas were viewed by two dimensional and color Doppler ultrasonography.Results Eighty-four cases were confirmed by pathology report that seventy-eight cases were ovarian teratomas.The accurate rate of ultrasound diagnosis was 92.9%(78/84).Among these cases,tumors which on the single side existed in sixty-nine cases (two tumors existed on the same side in two cases),and which on double sides existed in nine cases.Eighty-nine tumors were checked out all together.The ultrasonographic images of the ovarian teratomas displayed three types: mix(65 masses) , false solid (14 masses) and cyst (10 masses) type. Mix type was the major (occupied 65/89,73.0%). Multiplicate signs are shown in all of them. Malignant teratomas (3 masses,4 masses) not only appeared similar,but also more complex than the benign.Conclusions Ultrasonography is the first examination to be selected to diagnose teratoma of the ovary. Their ultrasonographic images are charaeteristic. If the images appears disorderly inside, the malignancy should be predicted with other clinical materials.
