Abstract:

Objective To evaluate the diagnostic value of multi⁃slice spiral CT（MSCT）enhanced scan⁃ ning in diagnosing the serous borderline ovarian tumor（S⁃BOT）and mucinous borderline ovarian tumor（M⁃BOT） based on the pathological diagnosis. Methods The preoperative imaging，clinical and pathological data of 39 cases of S ⁃BOT and 46 cases of M ⁃BOT confirmed by surgical pathology were retrospectively analyzed in our hospital， and the MSCT manifestations of the tumors were analyzed and compared. Results Taking the pathological results as the gold standard，MSCT enhanced scanning had a sensitivity of 87.2%，a specificity of 89.1%，an accuracy of 88.2%，and a Kappa value of 0.763 in the diagnosis of S⁃BOT and M⁃BOT. S⁃BOT and M⁃BOT had statistically significant differences in chamber distribution，homogenization of cystic fluid，thickening of the cyst wall/septum， maximum diameter of the mass，the CT value and the enhancement degree of the solid component（P＜0.05）. S⁃BOT mostly appeared as a single or double chamber cyst，M ⁃BOT showed mostly multi ⁃chamber performance；S ⁃BOT cystic fluid density was more homogenous than that of M⁃BOT；M⁃BOT was more common than S⁃BOT in the thick⁃ ening of the wall / septum；The maximum diameter of S⁃BOT was smaller than that of M⁃BOT；the solid component CT scan value of S⁃BOT was lower than that of M⁃BOT；both S⁃BOT and M⁃BOT showed delayed enhancement． The enhancement rate of S⁃BOT in each phase was higher than that of M⁃BOT. Hemorrhage and calcification had no statistical difference between the S ⁃BOT and the M ⁃BOT（P＞0.05）. Multivariate logistic regression showed that the characteristics of the chamber distribution，thickening of the wall/septum and the CT value of the solid compo⁃ nent had independent predictive value in identifying S⁃BOT and M⁃BOT. Conclusion MSCT enhanced scanning had a good consistency between the diagnosis of S⁃BOT and M⁃BOT and pathological diagnosis，and it may be used as an effective approach for the differential diagnosis of S⁃BOT and M⁃BOT.
