Contribution of vaginal scanning to sonographic evaluation of endometrial cancer invasion.
Vaginal sonography was compared to abdominal sonography in predicting myometrial invasion in 23 women (mean age 59 +/- 9 years) undergoing hysterectomy due to endometrial cancer. Vaginal scanning prediction corresponded to histological findings in 87% (20/23) of the cases. In 2 cases the degree of invasion was underestimated and in 1 case overestimated by vaginal sonography. Abdominal sonography was accurate in 78% (18/23) of the cases. Vaginal scanning also improved the sonographic visualization of endometrium and cervical canal. However, in one case a superficial invasion of the cervix was missed by both methods of scanning. Furthermore, in another patient an ovarian cyst of 5 cm located in the upper pelvis was seen by abdominal but not vaginal sonography. We suggest that a sonographic work-up to assess endometrial cancer spread should include both methods of scanning.
