目的分析卵巢囊性成熟性畸胎瘤超声诊断及鉴别特点,以减少超声误诊率。方法选择卵巢囊性成熟性畸胎瘤89例,平均年龄38岁。行腹部及经阴道超声检查,探查瘤体大小及内部回声特点,并与手术病理做对照。结果本组89例,肿物92枚,左侧46例,右侧40例,双侧3例。其中卵巢囊性成熟性畸胎瘤声像图呈囊实性65枚,类实性18枚,囊性9枚;误诊11枚,其中囊性9枚,囊实性1枚,类实性1枚。结论卵巢囊性成熟性畸胎瘤囊内呈中高回声,若形成特征性的改变则是超声诊断的依据;若缺乏其特征性,则是误诊的主要原因。超声鉴别诊断有一定作用,但需结合临床及病理。 Objective To analyze the characteristics of ultrasound diagnosis and differential diagnosis of ovarian cystic teratoma in order to reduce the misdiagnosis rate of ultrasound. Methods 89 cases of ovarian cystic teratoma were selected, with an average age of 38 years. Line abdominal and transvaginal ultrasound examination, explore the size of the tumor and internal echo characteristics, and with surgical pathology. Results The group of 89 cases, 92 cases of tumor, the left 46 cases, 40 cases of right and bilateral in 3 cases. Ovarian cystic teratoma in which the cyst was 65 cases of solid, 18 cases of solid, cystic 9; misdiagnosed 11, including cystic 9, cystic solid 1, the type of solid 1 Pieces. Conclusions Ovarian cystic maturation teratoma presents with hypoechoic cyst. If the characteristic changes are formed, it is the basis of ultrasonic diagnosis. If it is lack of its characteristic, it is the main reason of misdiagnosis. Differential diagnosis of ultrasound has a role, but need to combine clinical and pathological.
