卵巢囊性肿瘤的多层螺旋CT分析

MSCT analysis of ovarian cystic tumor

目的探讨卵巢囊性肿瘤的CT表现和诊断价值。方法回顾性分析28例共30个经手术病理确诊的卵巢囊性肿瘤的CT表现。CT平扫28例,同时增强扫描26例。结果 28例卵巢囊性肿瘤中,囊腺瘤10例(浆液性囊腺瘤7例、黏液性囊腺瘤3例),囊性畸胎瘤3例,囊腺癌8例(浆液性囊腺癌3例、黏液性囊腺癌5例),卵黄囊瘤4例,kruken-berg瘤1例,透明细胞癌2例。各种肿瘤因其性质(良、恶性)不同而具有相应特征性CT表现,与手术病理对照,准确地定性诊断24例(85.7%),误诊4例(14.3%),准确定位27例(96.4%),错误定位1例(3.5%)。结论卵巢囊性肿瘤的CT表现有一定特征性,CT对卵巢囊性肿瘤的诊断及鉴别诊断具有一定帮助。

Objective To explore the imaging features and diagnostic value of cystic tumor.Methods The CT features in 28 cases of cystic tumors（30 lesions） proven by surgery and pathology were studied retrospectively.All of the cases underwent CT scan and 26 cases underwent contrast-enhancement CT scan.Results The lesions included cystadenoma in 10 cases（serous cystadenoma in 7 cases,mucinous cystadenoma in 3 cases）,cystic teratoma in 3 cases,cystadenocarcinoma in 8 cases（serous cystadenocarcinoma in 3 cases,mucinous cystadenocarcinoma in 5 cases）,yolk sac tumor in 4 cases,krukenberg in 1 case,ovary clear cell carcinoma in 2 cases.Various tumors with its natures（benign or malignant） had a corresponding characteristic CT findings.Compared with surgery or pathology findings,25 of 28 cases（85.7%） were accurately diagnosed while other 3 cases（14.3%） were misdiagnosed,27 cases（96.4%） were correctly localized while other 1 case（3.5%） were erroneously localized.Conclusion There are some characteristics in the CT appearance of cystic tumors,and these characteristics may be helpful in predicting a specific for cystic tumors.
