螺旋CT增强扫描对卵巢囊腺瘤与囊腺癌的诊断价值

目的探讨螺旋CT增强扫描对卵巢囊腺瘤与囊腺癌的诊断价值。方法对38例42个经手术病理证实的卵巢囊腺癌(瘤)的CT表现进行回顾性分析。结果38例中,浆液性囊腺瘤5例,粘液性囊腺瘤3例,浆液性囊腺癌19例,粘液性囊腺癌11例;42个病灶其中表现为囊肿型(Ⅰ型)8个,囊实型(Ⅱ型)32个,实质型(Ⅲ型)2个。囊实型病灶以囊性为主(Ⅱa型)14个,混合性(Ⅱb型)15个,以实性为主(Ⅱc型)3个;增强后扫描,囊实型与实质型病灶实质明显强化。结论卵巢囊腺瘤常表现为Ⅰ型,卵巢囊腺癌以Ⅱ型常见;螺旋CT增强扫描使病灶特征得以很好显示,在鉴别卵巢囊腺性肿瘤良恶性方面有一定价值。

Diagnosis of the ovarian cystadenoma and cystadenocarcinoma by contrast enhanced spiral CT

Objective To discuss the contrast enhanced spiral CT diagnostic value in the ovarian cystadenoma and cystadenocarcinoma.Methods CT findings in 38 patients with pathologically-proved ovarin cystadenocarcinoma(cystadenoma)were retrospectively analyzed .Results 5 patients were serous cystadenoma , 3 patients were mucinous cystadenoma, 19 patients were serous cystadenocarcinoma, 11 patients were cystadenocarcinoma .The tumors were classified as cystic (typeⅠ, n=8), cyst-solid (typeⅡ, n=32) and solid types (type Ⅲ, n=2), cyst-solid type was further subdivided into subtype Ⅱa (mainly cystic, n=14),Ⅱb (mixed , n=15) and Ⅱc (mainly solid, n=3). On enhanced scan, type Ⅱand Ⅲ were obviously enhanced.Conclusion The ovarian cystadenoma often present as typeⅠ, while cystadenocarcinoma often present as type Ⅱ, the interior features of the tumors is more clearly revealed by contrast enhanced spiral CT, it has an important clinical value in diagnosis and differential diagnosis of the ovarian cystadenoma and cystadenocarcinoma.
