卵巢囊腺瘤的MRI诊断及鉴别诊断

MRI Diagnosis and Differential Diagnosis of Ovarian Cystadenoma

目的探讨磁共振成像(MRI)在卵巢囊腺瘤诊断中的价值。方法对20例22个病变经术后病理证实为卵巢囊腺瘤的MR表现进行回顾性分析。结果 22个病变中,病理证实浆液性囊腺瘤12个;粘液性囊腺瘤9个;混合性囊腺瘤(局灶交界性)1个。与病理结果相对照,MRI诊断良性囊腺瘤的准确率为100%(7/7),与病理诊断符合率为81.8%(18/22)。结论 MRI成像能很好的显示肿瘤的形态及信号特点,对卵巢肿瘤定位、定性有很大的帮助,为卵巢囊腺瘤的临床诊断、治疗提供充分的影像学依据。

Objective To investigate the value of magnetic resonance imaging （MRI） on the diagnosis of ovarian cystadenoma. Methods 22 lesions of 20 cases confirmed by postoperative pathology were reviewed. Results of 20 cases, 22 lesions were found, including 12 serous cystadenoma; 9 mucinous cystadenoma; 1 Mixed cystadenoma （focal border）. As compared with pathological results, the accuracy rate of MRI diagnosis was 100%（7/7）, and coincidence rate was 81.8%（18/22）. Conclusion MRI can clearly display tumor morphology and signal characteristics, it is very helpful for pelvic huge lumps of location and determination on the nature. MRI provide imaging guidance for clinical diagnosis and treatment of ovarian cystadenoma.
