Abstract:
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.
