卵巢原发性恶性肿瘤的MSCT诊断（附61例报告）

目的 探讨多层螺旋CT在卵巢恶性肿瘤诊断中的临床应用价值.方法 回顾性分析经手术病理证实的61例卵巢恶性肿瘤的多层螺旋CT影像学表现及诊断准确性.结果 多层螺旋CT清楚显示61例卵巢恶性肿瘤病变;术前多层螺旋CT诊断卵巢恶性肿瘤53例,符合率为86.9 %.其中浆液性囊腺癌35例（66 %）,黏液性囊腺癌15例（28 %）,浆液-黏液混合性囊腺癌1例（1.8 %）,子宫内膜样癌3例（5.7 %）,胚胎癌2例（3.8 %）,未成熟畸胎瘤5例（9.4 %）.结论 多层螺旋CT能较清楚地显示卵巢恶性肿瘤的特征,有助于临床诊断,并为卵巢恶性肿瘤治疗方案的选择及预后的判断提供更为全面的信息.

Multi-slice spiral CT diagnosis of ovarian malignancy: report of 61 cases

Objective To determine the value of multi-slice spiral CT （MSCT） tor diagnosing ovarian malignancy. Methods CT scans of 61 patients with pathologically proven ovarian malignancy were reviewed to assess the imaging appearances and accuracy of diagnosis. Results MSCT demonstrated clearly the imaging features of all 61 cases of ovarian malignancy. 53 eases were correctly diagnosed by MSCT before surgery with accuracy rate of 86.9%. The tumors included serous cysladenocarcinoma （35, 66%）, mucinous cystadenoearcinoma （15, 28%）, serous-mucinous cystadenocarcinoma （1, 1.8%）, endomelrioid carci noma （3, 5.7%）, embryonal carcinoma （2, 3.8%）, and immature teratoma （5, 9.4%）. Conclusion MSCT displays the imaging features of ovarian malignancy clearly, thus enabling accurate diagnosis. It can provide comprehensive intormation for treatment planning and prognosis.
