灰阶超声诊断卵巢囊性畸胎瘤的价值

Pathological Basis of Ovarian Cystic Teratoma and its Differential Diagnosis Using Grey Scale Ultrasonography

目的:探讨灰阶超声诊断卵巢囊性畸胎瘤的价值。材料和方法:对83例拟诊卵巢囊性畸胎瘤患者行灰阶超声检查,并与手术病理结果作对照。结果:灰阶超声拟诊卵巢囊性畸胎瘤83例,肿瘤91个,声像图特征分为6种类型:类囊肿型、类实质型、囊内面团征、囊内发团征、囊内脂液分层征、囊内杂乱征,其诊断符合率分别为81.0%、77.8%、96.2%、100%、100%和70.0%,超声诊断与术后病理诊断符合率为89.0%(81/91),漏误诊率为11.0%(10/91)。结论:灰阶超声特异征象对卵巢成熟性囊性畸胎瘤具有重要的诊断价值,但需与卵巢巧克力囊肿、卵巢黏液性囊腺瘤等进行鉴别。

Purpose To investigate the diagnostic value of gray scale ultrasound on ovarian cystic teratoma. Materials and Methods 83 patients with primary diagnosis of ovarian cystic teratoma underwent gray scale ultrasonography. The ultrasonic images were compared with postoperative pathologic results. Results 91 cases of 83 lesions were detected. The ultrasonic features were categorized into 6 types： cystoid, solid- like, intracystic dough sign, intracystic hair-ball, intracytic fat-fluid level, and intracytic cluttering sign. The diagnose accordance rate for each sign was 81.0%, 77.8%, 96.2%, 100% and 70.0%respectively. The diagnose accordance rate of ultrasonic diagnosis compared with pathologic results was 89.0% （81/91）, and misdiagnosed rate and rate of missing diagnosis was 11.0%（10/91）. Conclusion The ultrasonic features of ovarian cystic mature terotoma were of importance diagnostic value, whereas differentiation with ovarian chocolate cysts and ovarian mucus-cystic adenoma should be made cautiously.
