[摘要] 目的 探討卵巢透明細(xì)胞癌及漿液性腺癌的MR特征及鑒別診斷。 方法 回顧性分析2019年1月至2020年10月在我院經(jīng)手術(shù)病理證實(shí)的8例卵巢透明細(xì)胞癌及6例漿液性腺癌的臨床資料及腹盆腔MR平掃及增強(qiáng)表現(xiàn)特點(diǎn)，觀察腫塊的位置、大小、形態(tài)、信號(hào)及動(dòng)態(tài)增強(qiáng)特征。 結(jié)果 8例卵巢透明細(xì)胞癌單側(cè)發(fā)病8例（右側(cè)5例，左側(cè)3例），最大徑為3.9～16.1 cm，邊界清晰6例，邊界欠清2例，形態(tài)規(guī)則6例，不規(guī)則2例，囊實(shí)性病變8例;6例卵巢漿液性腺癌單側(cè)5例（右側(cè)3例，左側(cè)2例），雙側(cè)1例，最大徑為3.1～9.6 cm，邊界清晰2例，邊界不清4例，形態(tài)規(guī)則1例，不規(guī)則5例，囊實(shí)性病變6例。 結(jié)論 卵巢透明細(xì)胞癌MRI表現(xiàn)為體積較大、邊界清晰、形態(tài)規(guī)則的囊實(shí)性腫塊，實(shí)性成分表現(xiàn)為邊緣光滑突向囊內(nèi)的單個(gè)或多個(gè)壁結(jié)節(jié)，囊性成分所占比例較實(shí)性成分多;卵巢漿液性腺癌MRI表現(xiàn)為體積較小、邊界欠清、形態(tài)不規(guī)則的囊實(shí)性腫塊，實(shí)性成分表現(xiàn)為突向囊內(nèi)及囊外生長(zhǎng)的結(jié)節(jié)影，實(shí)性成分所占比例較囊性成分多。結(jié)合病史及不同影像表現(xiàn)，有利于對(duì)這兩種卵巢上皮性惡性腫瘤進(jìn)行鑒別診斷，為臨床提供有價(jià)值的影像信息。

[Abstract] Objective To explore the MR characteristics and differential diagnosis of ovarian clear cell carcinoma and serous adenocarcinoma. Methods Retrospectively analyzed the clinical data and the characteristics of unenhanced and enhanced abdominal pelvic MR of 8 cases of ovarian clear cell carcinoma and 6 cases of serous adenocarcinoma who were confirmed by surgery and pathology in our hospital from January 2019 to October 2020. The location， size， shape， signal， and dynamic enhancement characteristics of the mass were observed. Results Among the 8 cases of ovarian clear cell carcinoma， there were 8 cases with unilateral disease （5 cases on the right side， 3 cases on the left side）. The largest diameter was 3.9-16.1 cm. 6 cases had clear borders. 2 cases had unclear borders， 6 cases had regular morphology. 2 cases were irregular. 8 cases had cystic and solid lesions. Among the 6 cases of serous ovarian adenocarcinoma， 5 cases were unilateral （3 cases on the right side and 2 cases on the left side）， 1 case on both sides， with a maximum diameter of 3.1-9.6 cm， 2 cases with clear borders， 4 cases with unclear borders， 1 case with regular morphology， 5 cases with an irregular shape， and 6 cases with the solid capsule. Conclusion Ovarian clear cell carcinoma MRI shows a solid cystic mass with a large volume， clear borders， and regular morphology. The solid component manifested as single or multiple wall nodules with smooth edges protruding into the capsule， and the cystic component accounts for more than the solid component. The serous ovarian adenocarcinoma MRI shows cystic and solid masses with small volume， unclear borders， and irregular shapes. The solid component appears as nodules that protrude into and out of the cyst. The solid component accounts for a larger proportion than the cystic component. Combining the medical history and different imaging manifestations is beneficial to the differential diagnosis of these two ovarian epithelial malignancies and provides valuable clinical imaging information.
