| 中文摘要:目的探讨卵巢性索间质肿瘤的CT特点，以提高此类肿瘤的诊断水平。方法回顾性分析经手术病理证实的17例卵巢性索间质肿瘤的CT资料，分析其特点。结果17例卵巢性素间质肿瘤中卵泡膜细胞瘤7例，纤维瘤5例，颗粒细胞瘤4例，纤维-卵泡膜细胞瘤1例。肿瘤形态呈类圆形或卵圆形，边缘清楚，其中实性为主肿瘤14例，囊实性3例；肿瘤大小在2.1~15.0cm之间，平均为8.7cm。CT平扫17例均呈软组织密度肿块，内可有散在小囊状低密度区，增强扫描肿瘤实质无强化或仅有轻微强化；有2例增强后肿瘤内见纤细血管影，其他合并腹腔积液7例，子宫内膜增生4例，子宫内膜癌2例，子宫肌瘤7例。结论卵巢性索间质肿瘤表现为边界清晰的实性肿块，CT表现具有一定的特征，结合患者的临床表现有助于提高这类肿瘤诊断准确率，但确诊仍需要依靠病理。 |

| Abstract:ObjectiveTo study the CT manifestations of ovarian sex cord-stromal tumor, and to improve the diagnostic level for this tumor. MethodsCT data of ovarian sex cord-stromal tumor in 17 cases proved by surgery and pathology were analyzed retrospectively. ResultsOf the 17 ovarian sex cord-stromal tumor, 7 cases were ovarian thecoma, 5 cases were fibromas, 4 cases were granulose tumor and 1 case was fibroma-thecoma.The tumors were nearly round or elliptic, borders clear. Among them, 14 cases were solid tumors,3 cases were cystic.The size of the tumors ranged from 2.1-15.0cm,and the average size was 8.7cm. 17 cases of CT manifestations were density of soft tissue masses, and scattered cystic of low-density area. Those tumors had no enhancement or enhanced slightly. Two cases showed the slim vessel after enhanced,and other were associated with ascites (n=7), endometrial hyperplasia (n=4), endometrial carcinoma (n=2), hysteromyoma (n=7). ConclusionThe manifestations of ovarian sex cord-stromal tumor were borders clear of solid masses. It possesses characteristic features. Although CT combined with the clinical manifestations of patient could improve the diagnostic accuracy, but diagnosis also needed pathology. |
