Roca LF, Alshehri ED, Goldberg HR, et al. - The diagnostic performance of a Volume and Solid Vascular Tissue Score (VSVTS) for preoperative risk assessment of pediatric and adolescent adnexal masses was determined via performing a retrospective cohort study of 169 females with 179 masses that were managed surgically. The malignancy rate of 10.6% was observed. For pre-operative risk stratification of adnexal masses in the pediatric and adolescent population, improvement of positive predictive value was noted in correlation with using a sonographic scoring system based on the volume and presence of solid vascular tissue vs existing ultrasound-only approaches.
