Objective

To explore the use of the ovarian vascular pedicle sign(OVPS) as well as the diameters of ovarian veins to differentiate the fmales with a large pelvic mass on multidetector CT (MDCT).

Methods

In our study, from October 2006 to April 2011, we elected 297 patients, who had clinical diagnosis of gynecological tumor in our hospital. We observed retrospectively whether there was OVPS or not in each case with MDCT, and divided into patient group (n=208, the source of ovarian tumor involving the side) and the control group (n=386, non-ovarian source of ovarian tumors involving the side + the uninjured side). We measured the diameter of bilateral ovarian vein with MDCT. The pathological results was served as the golden standard, and diagnostic test was performed for OVPS.

Results

①Compared with the pathological results, results show that the presence of OVPS on MDCT was statistically significant (P<0.005) to differentiate the source of the ovarian tumor, and the sensitivity, specificity, positive predictive value and negative predictive value were 97.60%(203/208), 92.75%(358/386), 87.88%(203/231), 98.62%(358/363), and diagnostic accuracy rate was 94.44%(561/594). ② there was significant difference in the diameter of the ovarian veins between the mass side and contralateral side in the patients with an ovarian mass.

Conclusion

OVPS plays an important role in locating the source of ovarian tumor in females with a large pelvic mass. and the value of the diameter of the ovarian veins in differentiating ovarian origin or not was low.
