【摘要】：目的探讨卵巢少见原发性肿瘤的CT表现及特征,以提高对该类疾病的诊断及鉴别诊断能力。方法回顾性分析经手术病理证实的19例卵巢少见原发性肿瘤的CT表现并复习相关文献。结果卵巢子宫内膜样癌4例,为单侧附件区囊实性肿块,实性部分及分隔中等度强化。卵泡膜细胞瘤-纤维瘤组肿瘤6例,为密度不均实性或囊实性表现,实性部分轻度强化或强化不明显;硬化性间质瘤2例,为囊实性肿块,呈类似肝脏血管瘤样的强化;淋巴瘤1例,盆腔巨大囊实性肿块,边界尚清,实性部分中度强化,腹腔见积液及肿大淋巴结;颗粒细胞瘤3例,典型者呈多房蜂窝状囊性表现,边界清晰,实性部分及分隔呈轻中度强化;无性细胞瘤1例,呈分叶状,为实性肿块,内见低密度纤维分隔,实性部分中度强化;Brener瘤2例,呈实性肿块,均见团片状钙化灶。结论卵巢少见原发性肿瘤的CT表现具有一定的特征性,且CT也是目前较为常用、方便的术前检查手段,能充分显示病变与周围组织的关系及血供特点,但最后确诊仍须结合临床及完整的病理资料分析。
[Abstract]:Objective to investigate the CT features of rare primary ovarian tumors in order to improve their diagnostic and differential diagnosis. Methods CT findings of 19 rare primary ovarian tumors confirmed by surgery and pathology were analyzed retrospectively. Results there were 4 cases of ovarian endometrioid carcinoma, which were unilateral adnexal cystic solid mass with moderate enhancement of solid part and septum. In the follicular cell tumor-fibroma group, 6 cases showed heterogeneous density or cystic solid, with slight enhancement or no enhancement, sclerosing stromal tumor (sclerosing stromal tumor 2 cases, cystic solid mass, similar to hepatic hemangiomatous enhancement), sclerosing stromal tumor (sclerosing stromal tumor) in 6 cases, which was similar to hepatic hemangiomatous enhancement. One case was lymphoma with large cystic and solid pelvic mass, the boundary was still clear, the solid part was moderately enhanced, effusion and enlarged lymph nodes were seen in abdominal cavity, and 3 cases of granulosa cell tumor showed multilocular honeycomb cystic appearance with clear boundary. One case of asexual cell tumor presented lobular mass with low density fibrous septum and 2 cases with solid partial moderate enhancement of Brener tumor. Conclusion CT findings of rare primary ovarian tumors have some characteristics, and CT is a relatively common and convenient means of preoperative examination, which can fully show the relationship between lesions and surrounding tissues and the characteristics of blood supply. However, the final diagnosis must be combined with clinical and complete pathological data analysis.
