Methods After surgery 28 cases of pathologically confirmed Ultrasonographic characteristics of struma ovarii were retrospectively analyzed.
方法对经手术病理证实的28例卵巢甲状腺肿超声声像特征进行回顾分析。
Results 28 cases in the ultrasound examination can correctly diagnosed only 8 cases of struma ovarii, accounting for 28.5%, the majority of misdiagnosed as ovarian malignancy.
结果28例中超声检查能够正确诊断为卵巢甲状腺肿仅8例，占28.5%，大多数误诊为卵巢恶性肿瘤。
Results The incidence of the struma ovarii was 3.75% in mature teratoma of ovary. The clinical features were non-specific pelvic tumor or no symptom found in the patients in physical examination.
结果本病发病率在卵巢成熟畸胎瘤中占3 .75 % ，临床表现为非特异型盆腔肿块，或无症状被体检发现。
