• W1990332317 abstract "Study ObjectiveTo determine the role of pre-operative 3D and 3D power Doppler (PD) transvaginal sonography (TVS) in discriminating between benign, borderline and malignant adnexal masses; in patients with previous ultrasound and magnetic resonance (MRI) or computerized tomography (CT) with inconclusive results.DesignProspective study comparing the results of pre-operative 2D/3D/PD TVS to histopathologic findings at surgery.SettingUniversity based community hospital.Patients40 consecutive women with multilocular, cystic-solid or solid adnexal masses.Intervention2D/3D/PD TVS examination was used to evaluate volume, morphology, and vascularization of the adnexal masses based on 3D surface rendering. 3D PD sonography was used to assess vascularization and vascular indices (vascularization index [VI], flow index [FI], and vascularization-flow index [VFI]) were automatically calculated. A definitive histologic diagnosis was obtained in each case.Measurements and Main ResultsOf the 40 ovarian masses: 7 were malignant, 7 were borderline and 26 were benign. 3D TVS correctly diagnosed 23 cases, was uncertain in 11, and was incorrect in 6. Incorrect or uncertain TVS diagnosis was more common in patients with borderline (6) and benign (7) lesions. Of the 25 unilocular solid and 10 multilocular solid masses, an irregular wall or papillary surface was detected by 3D morphologic evaluation in 83% of the malignant, 85% of the borderline, and 15% of the benign masses. The mean VI (13.3% versus 6.2% versus 4.8%; P <0.05) was significantly higher in malignant compared to borderline and benign lesions, however mean VI did not differ significantly between benign and borderline.ConclusionIn patients with “difficult” adnexal tumors, 3D PD TVS could be helpful improving the diagnostic accuracy especially for benign cystic-solid and solid adnexal masses. The differentiation between borderline and benign tumors seems to be based more on the 3D irregular aspect of cystic wall or papillary surface than on vascular indice, whereas, VI seems more significant in distinguishing borderline from malignant tumors.
