目的分析和总结良恶性卵巢肿瘤的MRI表现,提出良恶性卵巢肿瘤的诊断和鉴别诊断价值。方法分析了39例经手术和病理证实的卵巢肿瘤的MRI资料,包括良性肿瘤22例,恶性肿瘤17例,并与病理结果对照。结果术前MRI诊断的39例卵巢肿瘤中单侧病灶25例,双侧病灶14例,卵巢病灶共53个。术前诊断卵巢良性肿瘤38个,恶性肿瘤15个。术后病理诊断良性肿瘤36个,恶性肿瘤17个。结论①MRI有良好的组织对比分辨率,对畸胎瘤、卵巢子宫内膜异位囊肿、卵巢囊肿、囊腺瘤等病变可以作出定性诊断。②MRI能准确显示卵巢肿块的大小、形态和侵及范围,有助于定性诊断和区分肿瘤的良恶性。
Objective To analyze and summarize the MRI findings of benign and malignant ovarian tumors and to provide the diagnostic and differential diagnostic value of benign and malignant ovarian tumors. Methods MRI data of 39 cases of ovarian tumors confirmed by surgery and pathology were analyzed, including 22 cases of benign tumors and 17 cases of malignant tumors, which were compared with the pathological results. Results Among 39 ovarian tumors diagnosed by preoperative MRI, 25 were unilateral lesions, 14 were bilateral lesions and 53 were ovarian lesions. Preoperative diagnosis of ovarian benign tumors 38, 15 malignant tumors. Postoperative pathological diagnosis of 36 benign tumors, 17 malignant tumors. Conclusion ① MRI has a good resolution of tissue contrast, teratoma, ovarian endometriosis, ovarian cyst, cystadenoma and other lesions can make a qualitative diagnosis. ②MRI can accurately show the size, shape and invasion of ovarian tumor range, contribute to the qualitative diagnosis and distinguish between benign and malignant tumors.
