@entity1 @entity43 @entity39 @entity4 @entity5274
PURPOSE: Torsion angle determines the incidence of @entity39 among @entity1 with @entity43 . The purpose of this study was to evaluate the association between torsion angle and findings on CT scan. MATERIALS AND METHODS: We retrospectively reviewed CT scan findings obtained less than 36  h before surgery for 31 @entity1 with @entity43 . Ovarian torsion angles measured intraoperatively ranged from 90   to 1260  . Ovaries with torsion angles less than 360   rarely develop @entity39 . @entity1 were divided into two groups according to torsion angle:  <360   (Group A) and  >= 360   (Group B). A lesion corresponding to an @entity5274 and mesovarium containing dilated veins between the uterus and twisted ovary is referred to as a "mass-like @entity4 ". RESULTS: A mass-like @entity4 occurred more often in Group B (p  <  0.05) and had the highest correlation with torsion angles  >= 360  . A mass-like @entity4 lacking enhancement or a high-density area was significantly different between the groups (p  <  0.05) and was also indicative of torsion angles  >= 360  . CONCLUSION: A mass-like @entity4 alone or with a high-density area or lack of enhancement suggests an @entity43 angle  >= 360  . The presence of these findings predict @entity43 and may allow ovary-sparing treatment.
