卵巢囊腺瘤的CT诊断(附22例报告)

CT diagnosis of ovarian cystadenoma :a report of 22cases

目的确定CT对卵巢囊腺瘤的诊断价值。方法对超声诊断不满意的22例卵巢囊腺瘤的CT表现进行回顾性分析,并与手术病理所见进行了对照。结果22例卵巢囊腺瘤患者中,浆液性囊腺瘤见于15例,粘液性囊腺瘤5例,交界性粘液性囊腺瘤2例。与术后病理结果对照,CT正确诊断了22例中的21例(95%)。CT探测单侧单发性卵巢囊腺瘤病变的准确率为100%(n=22/22)。结论CT在卵巢囊腺瘤的诊断中,能清晰显示其内部特征及其病变与周围组织的关系,因而,它是一种可靠、有效的诊断方法。但是,CT对交界性卵巢囊腺瘤和卵巢囊腺瘤的恶变难以做出准确的定性诊断,多数情况下需经手术病理证实。

Objective To determine the value of computed to mography(CT)in the diagnosis of ovarian cystaden oma.Methods CT find-ings in 22patients with ovarian cystadenoma which was sonographically u nsatisfied were analyzed retrospectively and compared with that of the postoperative pathology.Results Among 22patients with ovarian cysta denoma,benign serous cystadenomas were found in 15cases,be-nign mucous cystadenomas in 5cases,and borderline mucous cystadenomas in 2cases.Compared with the postoperative pathology,before the operation CT correctly diagnose d 21of 22cases(95%).The accuracy of CT in the detection o f single -unilateral ovarian cystad enoma was 100%(n =22/22).Conclusion CT can clearly reveal the inner featu res of ovarian cystadenoma and the re lationship between the le-sions and the surrouding tissues,an d therefore it is a reliable and effec tive means for detecting ovarian cystadenoma but it will be difficult to make the qualitative diagnosis of borderline ovarian cystadenoma or i ts malignant changes,in most cases i t needs the demonstration by the postoperative pathology.[
