摘　　要：目的:通过分析卵巢恶性肿瘤的MRI征象,提高对卵巢恶性肿瘤的诊断水平。方法:搜集经手术病理证实的20例卵巢恶性肿瘤病例,其中卵巢上皮癌12例、卵巢恶性生殖细胞肿瘤2例、小细胞癌3例、淋巴瘤1例、转移瘤2例。所有病例均行MRI平扫及增强,回顾性分析其MRI征象。结果:卵巢恶性肿瘤MRI表现为肿块体积较大、形态不规则,与周围组织结构分界不清;肿块质地不均,其中囊性肿块4例,实性肿块4例,囊实性肿块12例,囊壁、壁结节和实性部分增强扫描均有明显强化。结论:不同病理类型卵巢恶性肿瘤的MRI表现有相似之处,分析其相关征象对卵巢恶性肿瘤的定性诊断具有重要意义。Objective：To improve the diagnosis level by analyzing the MRI features of malignant ovarian tumor（MOT）.Methods：20 patients with MOT confirmed by pathology were collected.There were 12 cases of epithelial ovarian cancer,2 cases of malignant ovarian germ cell tumor,3 cases of ovarian small cell carcinoma,1 case of lymphoma and 2 cases of metastases.Their MRI manifestations by plain and enhanced scanning were retrospectively analyzed.Results：The MRI manifestation of MOT were large in size,irregular in shape and unclear in boundaries with surrounding tissues.There were 4 cases of cystic mass with uneven texture,thick edge and mural nodules,4 cases of solid mass and 12 cases of cystic solid mass.Cystic wall,mural nodules and solid part of the mass all showed intensive enhancement after enhanced scanning.Conclusion：There are certain similarities and differences between MRI manifestations of different pathological types of MOT,analyzing them will lead us to a correct radiological diagnosis.
