title: The bright edge of the endometrial polyp.
abstract: OBJECTIVE
  To evaluate the accuracy of sonographic detection of endometrial polyps using a new ultrasound marker denoted 'the bright edge of the polyp'.
  
  
  METHODS
  The ultrasound scans of the uterus were examined for the presence of the bright edge in two groups of women. The first, a retrospective group, included 40 women in whom both a histological diagnosis of endometrial polyps and sonographic scans were available for evaluation. The second, a prospective group, included 80 women scheduled for operative hysteroscopy because of endometrial irregularities detected by sonography. In this group the hysteroscopical and histological results of the removed endometrial tissue were correlated with the sonographic diagnosis.
  
  
  RESULTS
  In the retrospective group, the bright edge marker, indicative of the presence of a polyp, was detected in 30 out of 40 scans available for evaluation. In the prospective group this marker was detected in 60 women out of 80. Endometrial polyps were confirmed in 56 of these 60 women. In three cases a submucosal myoma was found and in one case the histology showed simple cystic hyperplasia. Two polyps were found in 20 cases where the bright edge had not been detected. This marker has a sensitivity of 96%, specificity of 82%, positive predictive value of 93%, and negative predictive value of 90% in this group at high risk for endometrial abnormalities.
  
  
  CONCLUSIONS
  The bright edge of the polyp is an accurate sonographic marker for the detection of endometrial polyps in women with endometrial irregularities demonstrated on ultrasound.
