CT and TVS diagnostic evaluation of female pelvic masses

Purpose To evaluate the diagnostic value of female pelvic masses with CT and TVS. Methods 33 eases of female pelvic masses confirmed by operation and pathology were retrospectively studied with CT and TVS. Results It is of sensitivity to detect cystic change, calcification and pseudcapsule of uterine leiomyomas and irregular low - density area inside leiomyomas having been enhanced by CT scanning, nevertheless it tend to neglect submucosal leiomyoma contributing to deforming uterine cavity (accuracy rate71% ,5/7) . TVS scanning can provide accurate diagnosis of leiomyoma presenting circinate hypoechoic mass, whereas it tend to diagnose wrong to cystic change of leiomyoma resulting in non -echo focus and abnormal echoic mass inside uterine cavity (accuracy rate71% ,5/7). For 3 cases of endomentrioid adenocarcinoma, TVS scanning can accurately measure thickening of endometrium and detect irregular echo (accuracy rate 100% ,3/3). Corresponding to regular or irregular low -density area in the center of uterine in CT pattern, it lack of differentia (accuracy rate33% , 1/3). We carefully observed the fluids, the wall and septa of cyst and endocystic vegetations of ovarian cyst, endometriosis and ovarian cystadenaraa in combination with two imaging methods, improving accuracy rate obviously: ovarian cyst(100% ,4/4) , endometriosis(67% ,2/3), ovarian cystadenama(75% ,3/4) . It is of sensitivity to detect ter-atoma by CT thin- slice scanning, because of its containing calcification and lipid(accuracy rate 100% ,3/3) . Accuracy rate is 100% to differential diagnosis between malignant solid mass and benign solid mass by CT scanning. Because malignant tumors are often solid with lobulated and nodular borders and enhanced obvious, whereas benign tumors are solid with margmated borders and enhanced faint. TVS scanning only presents solid mass rather than diagnosing that of malignant or benign. Whether CT or TVS scanning, which must be in combination with clinic information to diagnose pelvic abscess. Conclusions CT combined with TVS can improve diagnostic accuracy in female pelvic masses.
