【摘要】 目的:探讨卵巢囊性成熟性畸胎瘤的声像图特征。方法:选择超声诊断或病理诊断卵巢囊性成熟性畸胎瘤93例102枚,行腹部及阴道超声检查,探查病体大小及内部回声特点,并与手术病理作对照。结果:95枚卵巢囊性成熟性畸胎瘤,囊实混合性68枚(71.6%),囊性15枚(15.8%),类实性10枚(10.5%),漏诊2枚(2.1%)。超声诊断88枚,漏诊2枚,误诊12枚,超声诊断准确率86.3%(88/102)。结论:结节状高回声、线条征与脂液分层征具有较高的敏感性与特异性,是卵巢囊性成熟性畸胎瘤的超声诊断与鉴别诊断的主要依据,肿物过小与缺乏特征性是漏误诊的主要原因。更多还原

【Abstract】 Objective:To study the ultrasonographic features of mature cystic ovarian teratomas in order to reduce ultrasonographic misdiagnosis.Methods:95 masses with mature cystic ovarian teratomas confirmed by operation and pathology were examined by ultrasonography and compared with operation and pathology.Results:The ultrasonographic images of 95 masses with mature cystic ovarian teratomas displayed three types:cystic and solid(68 cases),cystic(15 cases) and false solid(10 cases) type.14 cases were misdiagnosed.The rate of accuracy by ultrasonography in diagnosing mature cystic ovarian teratomas was 86.3%(88/102).Conclusion:Hyper-echo likenode and line-sign with high sensitivity and specificity are main presentation in diagnosis and differential diagnosis of mature cystic ovarian teratomas by ultrasonography, but too small mass and no-characteristic ultrasonography can cause misdiagnosis.更多还原
