目的 探讨超声对卵巢良、恶性畸胎瘤的诊断价值。方法 应用二维和彩色多普勒超声观察 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 6 9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(6 5枚 )、假实性 (14枚 )和囊性 (10枚 ) ,以混合性表现为主 (占 73.0 % ) ,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。
Objective To investigate the diagnostic value of ultrasound in benign and malignant teratoma of ovarian. Methods Two-dimensional and color Doppler ultrasonography were used to observe the sonographic characteristics of 84 cases of benign and malignant teratomas of the ovary. Results All 84 cases were confirmed by operation and pathology. 78 cases were teratoma patients. The coincidence rate of ultrasound diagnosis was 92.9%. Among them, 69 cases were unilateral (2 cases were 2 cases on one side) and 9 cases were bilateral. A total of 89 tumors were detected. There are three types of sonograms: mixed (6 5), false (14), and cystic (10), mainly mixed (73.0 %), accompanied by multiple forms Signs. Malignant teratoma (3 cases, 4 cases) showed more complex sonograms, but it was characterized by benign cystic teratoma. Conclusion Ultrasound is the preferred method for examination of ovarian teratoma, and the sonographic appearance of benign cystic teratoma is characteristic. If the internal echo of the tumor is more cluttered, it should be closely combined with the clinical, indicating the possibility of malignancy.
