35例卵巢囊腺瘤的MRI诊断及鉴别诊断

MRI in ovarian cystadenoma: a report of 35 cases

目的探讨磁共振成像对卵巢囊腺瘤的诊断意义及其表现特征。方法搜集资料完整并经病理证实的卵巢囊腺瘤35例,回顾性分析卵巢囊腺瘤的MRI表现。结果35例共有39个囊灶,其中15例浆液性囊腺瘤共有19个病灶(4例双侧卵巢发病);20例粘液性囊腺瘤均为单侧发病(包括交界性囊腺瘤3例)。5例为单囊病灶;30例为多囊多房性病灶,囊内有分隔,呈多房、破鱼网状、囊套囊状等,囊腺瘤囊壁一般较薄且规则,囊壁可有壁结节;单囊病灶信号均匀,多囊多房性病灶信号多不均匀。结论掌握卵巢囊腺瘤的MRI表现有一定特征性,MRI对卵巢囊腺瘤的定性诊断及鉴别诊断具有重要意义。

Objective To investigate the diagnostic value of MRI in ovarian cystadenoma. Methods MRI and pathological findings were retrospectively analyzed in 35 cases of ovarian cystadenoma. Results Of the 35 cases, there were 5 monolocular cysts and 30 multilocular cysts; 39 lesions were found, including 19 lesions in 15 serous cystadenomas and 20 lesions in 20 mucous cystadenomas. The cystic wall was generally thin and regular, and sometimes nodular. The multilocular cysts were multihole, broken net-like or polycircular, and showed the irregular signals, while the monolocular cysts showed the uniform signals. Conclusion MRI features are helpful in the diagnosis of ovarian cystadenoma.
