【摘要】：目的探讨卵巢支持-间质细胞肿瘤的CT表现特点。方法搜集经手术病理证实的8例卵巢支持-间质细胞肿瘤的CT资料,分析其CT表现。结果 8例卵巢支持-间质细胞肿瘤中,7例表现为边界清晰的囊实性或实性肿块,1例呈多房囊性,增强扫描囊壁壁结节明显强化,余7例实性成分有不同程度的强化,明显强化4例,中度强化2例,轻度强化1例。其中5例30岁,5例睾酮水平持续升高,2例泌乳素水平升高,3例AFP升高,2例CA125升高。免疫组织化学标记物中阳性表达前三位由高到低依次为:Inhibin-α(100%)、Vimentin(75%)、CD56(50%)。结论卵巢支持-间质细胞肿瘤在CT上多呈单侧附件区的实性或囊实性肿块,边界清楚,实性部分多强化明显,且呈进行性强化,结合临床发病年龄、激素水平异常,尤其是血清睾酮水平提高,以及免疫组织化学检查等有助于该病的诊断。
[Abstract]:Objective to investigate the CT features of ovarian Sertoli-interstitial cell tumor. Methods CT findings of 8 cases of ovarian Sertoli-interstitial cell tumor proved by operation and pathology were analyzed. Results among the 8 cases of ovarian Sertoli stromal cell tumor, 7 cases showed clear boundary cystic or solid mass, 1 case presented multiple locular cystic lesions, and the other 7 cases showed enhancement of solid components in different degree. There were obvious enhancement in 4 cases, moderate enhancement in 2 cases and mild enhancement in 1 case. Among them, 5 cases were 30 years old, 5 cases were testosterone level, 2 cases were prolactin level, 3 cases were AFP and 2 cases were CA125. The first three positive expressions in immunohistochemical markers from high to low were: Inhibin- 伪 (100%) Vimentin (75%) and CD56 (50%). Conclusion Ovarian Sertoli Leydig cell tumors present solid or cystic masses in unilateral adnexal area on CT scan, with clear boundary, obvious enhancement of solid part and progressive enhancement, combined with clinical onset age and abnormal hormone level. In particular, elevated serum testosterone and immunohistochemical examination are helpful in the diagnosis of the disease.
