超声对卵巢良、恶性畸胎瘤的诊断价值

目的 探讨超声对卵巢良、恶性畸胎瘤的诊断价值。方法 应用二维和彩色多协超声观察84例卵巢良、恶性畸胎瘤的声像图特征。结果 84例均经手术和病理证实，78例为畸胎瘤患者，超声诊断符合率为92．9％。其中单侧的69例（2例为一侧2枚瘤体），双侧的9例，共查出89枚瘤体。声像图表现为三种类型：混合性（65枚）、假实性（14枚）和囊性（10枚），以混合性表现为主（占70％），并伴有多种形态征象。恶性畸胎瘤（3例，4枚）声像图表现更为复杂，但具有良性囊性畸胎瘤的特征。结论 超声是卵巢畸胎瘤的首选检查方法，其中良性囊性畸胎瘤声像图表现具有特征性。如肿瘤内部回声更加杂乱，应密切结合临床，预示恶性可能。

The value of ultrasonography in diagnosing of benign and malignant ovarian teratomas

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.
