目的 探讨绝经妇女卵巢肿瘤的临床及超声声像图特征。方法 回顾性分析经手术证实的130例绝经后妇女卵巢肿瘤的临床资料及超声声像图特点。结果 良性肿瘤 94 例（72.3%），恶性肿瘤 36例（27.7%），绝经后卵巢肿块双侧病变的恶性率大于单侧病变者; 单侧卵巢肿块最大径线 ＞10 cm 的恶性率大于最大径线≤10 cm 者; 囊实性包块中多个分隔无助于良恶性的判断，有腹水者恶性率大于无腹水者。超声检查结果与病理结果对照符合104例，准确率为80%。结论 超声声像图特征可为绝经后卵巢肿瘤的良恶性鉴别提供重要依据； 绝经后浆液性囊腺瘤、成熟畸胎瘤、子宫内膜异位症的超声诊断准确率较绝经前高；少见卵巢肿瘤的超声诊断准确性还有待进一步提高。

Objective To investigate the ultrasonographic features of ovarian tumor and clinical data of the postmenopausal women. Methods The features of ultrasonography and clinical data of 130 postmenopausal woman patceuts with ovarian tumor were retrospectively analyzed. Results A total of 94 cases of benign tumor were observed (72.3%) and malignant tumors were in 36 cases (27.7%). The malignant rate of bilateral lesions was higher than that of unilateral lesions; the malignant rate of unilateral ovarian tumor with the maximum diameter ＞ 10 cm was higher than that of unilateral ovarian tumor with the maximum diameter≤10 cm. Polyseptations in solid masses failed to help differentiate benign masses from malignant masses. The malignant rate of ascites was higher than that without ascites. In 104 cases the results of ultrasonography were consistent with pathological findings. The accurate rate of ultrasonography was 80%. Conclusions The ultrasonographic features are important basis to identify the nature of the tumor. Ovarian serous cystadenoma, teratoma and endometriosis in the postmenopausal women are diagnosed with higher accurate rates than those in the premenopausal women. The accurate rates of diagnosis for the rare ovarian tumor need to be futher improved.
