【摘要】：目的探讨卵巢无性细胞瘤的CT、MRI特征及临床治疗。方法回顾性分析13例病理证实的卵巢无性细胞瘤的CT、MRI及临床资料。结果 12例单发,1例双侧多发。单纯型11例,混合型2例。肿瘤体积大,边界清晰。CT表现:6例实性肿块,1例囊实性。增强动脉期6例不均匀轻-中度强化,4例见明显强化肿瘤血管;1例不均匀明显强化;静脉期持续强化。MRI表现:9例实性肿块,T1WI等或稍低信号,T2WI等或稍高信号;增强动脉期不均匀轻-中度强化,4例见迂曲肿瘤血管,静脉期持续强化。1例多房囊性肿块,增强动脉期分隔及囊壁明显强化,静脉期持续强化呈高信号。随访时间3~90个月,11例未复发,1例术后3年复发,1例术后2年死亡。结论卵巢无性细胞瘤具有一定的影像学特征,综合分析其影像特征,可以在术前做出初步诊断,结合术后3~6个疗程方案化疗可实现良好预后,手术的目的是尽可能切除病灶,使化疗发挥最大的疗效。
[Abstract]:Objective to investigate the CT MRI features and clinical treatment of ovarian asexual tumor. Methods CT MRI and clinical data of 13 cases of pathologically proved ovarian asexual tumor were retrospectively analyzed. Results 12 cases were single and 1 case had bilateral multiple. There were 11 cases of simplex type and 2 cases of mixed type. The size of the tumor was large and the margin was clear. Ct findings showed that 6 cases had solid mass and 1 case had cystic solid tumor. In 6 cases of non-homogeneous mild to moderate enhancement of arterial phase, 1 case showed obvious enhancement of tumor vessels, 9 cases of solid mass showed T1WI or hypointensity on T2WI or slightly hyperintense, and 1 case showed non-homogeneous enhancement in venous phase, and 9 cases showed T1WI or hypointensity on T2WI in 9 cases of solid mass. In 4 cases of nonhomogeneous mild to moderate enhancement of arterial phase, the vessels of tortuous tumor were found in 4 cases, and the continuous enhancement of 1 cases of multilocular cystic mass in venous phase, enhanced arterial phase separation and obvious enhancement of cystic wall, and continued enhancement of venous phase showed high signal intensity. The follow-up time was 3 ~ 90 months, 11 cases had no recurrence and 1 case had recurrence 3 years after operation and 1 case died 2 years after operation. Conclusion Ovarian asexual cell tumor has some imaging features. Comprehensive analysis of its imaging features can make a preliminary diagnosis before operation, combined with 3 ~ 6 courses of chemotherapy after surgery can achieve a good prognosis, the purpose of the operation is to remove the focus as much as possible. To maximize the efficacy of chemotherapy.
