目的探讨超声在良、恶性卵巢畸胎瘤鉴别诊断中的应用价值。方法应用经腹及阴道内二维和彩色多普勒超声观察经手术和病理证实的54例卵巢良、恶性畸胎瘤患者的声像图特征。结果54例为畸胎瘤患者,44例为良性畸胎瘤,10例为恶性畸胎瘤。良性畸胎瘤患者共检出64枚瘤体,声像图表现为三种类型:类囊肿型(7枚),混合型(46枚),类实性肿物型(11枚);以混合性表现为主(占71.9%),并伴有多种形态特征。恶性畸胎瘤(10例),图像特征较为复杂,除具有良性畸胎瘤的特征,内部回声更加杂乱。结论超声是诊断卵巢畸胎瘤的首选方法。良性畸胎瘤声像图表现有其特征性,成熟畸胎瘤彩色多普勒检查,肿块内或边缘几乎未见血流信号,经腹及阴道超声检查结合彩色多普勒血流显像,可提高畸胎瘤诊断率及鉴别诊断水平。
Objective To investigate the value of ultrasound in the differential diagnosis of benign and malignant ovarian teratoma. Methods The transabdominal and intravaginal two-dimensional and color Doppler ultrasound was used to observe the pathological features of 54 cases of benign and malignant ovarian teratoma in patients with sonographic features. Results 54 cases of teratoma patients, 44 cases of benign teratoma, 10 cases of malignant teratoma. A total of 64 tumors were detected in patients with benign teratoma, with three types of sonograms: cystoid (7), mixed (46), solidoid (11); mixed Mainly sexual performance (71.9%), accompanied by a variety of morphological characteristics. Malignant teratoma (10 cases), the image features more complex, in addition to having the characteristics of benign teratoma, the internal echo more messy. Conclusion Ultrasound is the preferred method of diagnosis of ovarian teratoma. Benign teratoma has its own characteristic sonogram, mature teratoma color Doppler examination, almost no blood flow within the tumor mass or edge signal, transabdominal and vaginal ultrasound combined with color Doppler flow imaging, Teratoma can improve the diagnosis rate and differential diagnosis.
