MSCTA对卵巢上皮癌与上皮性交界性肿瘤的鉴别诊断价值

目的 探讨多层螺旋CT血管成像(MSCTA)对卵巢上皮癌(EOC)与卵巢上皮性交界性肿瘤(BOT)的鉴别诊断价值.方法 回顾性分析经手术病理证实的39例EOC及23例BOT的MSCTA特异征象,其中主要分析的征象有:供血动脉的数目、有无粗大引流静脉、肿瘤内血管是否走行迂曲及布局紊乱、是否合并小动脉瘤、是否合并动静脉瘘.结果 EOC组及BOT组供血动脉数目≥2支者分别占89.7%(35/39)和8.7%(2/23);显示粗大引流静脉者分别占87.2%(34/39)和4.3%(1/23);肿瘤内血管走行迂曲、布局紊乱者分别占97.4%(38/39)和13.0%(3/23);出现小动脉瘤者分别占79.5%(31/39)和8.7%(2/23);出现动静脉瘘者分别占74.4%(29/39)和4.3%(1/23).2组各MSCTA特征差异均有统计学意义(P均<0.01),并具有较高的特异性及高敏感性.结论 MSCTA可较好地显示肿瘤血管的分布、数量及形态,对EOC与BOT的鉴别诊断具有重要价值.

The value of MSCTA in differential diagnosis between epithelial ovariancarcinoma and borderline epithelial ovarian tumor

Objective To evaluate the value of multislice spiral computed tomography angiography (MSCTA) in differential diagnosis between epithelial ovarian carcinoma (EOC) and borderline epithelial ovarian tumor (BOT).Methods The MSCTA images of 39 EOC patients and 23 BOT patients confirmed by surgical pathology were reviewed retrospectively.Main characteristics of tumor vessels were analyzed: the number of feeding arteries, the existence of dilated draining veins, whether the tumor vessels were tortuous, whether the distribution of tumor vessels were disturbed, and whether there were accompanying microaneurysms or arteriovenous malformations (AVMs).Results Two or more feeding arteries of the EOCs and BOTs were 89.7% (35/39) and 8.7% (2/23), respectively.Dilated draining veins were observed in 87.2% (34/39) of the EOCs and 4.3% (1/23) of the BOTs.The tortuosity of tumor vessels was observed in 97.4% (38/39) of the EOCs and 13.0% (3/23) of the BOTs.79.5% (31/39) of the EOCs and 8.7% (2/23) of the BOTs were complicated by microaneurysms, and 74.4% (29/39) of the EOCs and 4.3% (1/23) of the BOTs were complicated by AVMs.The characteristics of tumor vessels were significantly different between the two groups (P<0.01), with relatively high sensitivity and specificity.Conclusion MSCTA can better show the distribution, number and pattern of tumor vessels and is of great value in differential diagnosis between EOC and BOT.
