Objective: To determine the most discriminating two-dimensional gray-scale and colour Doppler sonographic features that allow differentiation between malignant and benign adnexal masses, and to develop a scoring model that would enable more accurate diagnosis with those features.
Methods: A cross sectional prospective study was conducted on patients scheduled for surgery due to presence of adnexal masses at Gyneoncology Unit of Alshatby hospital, Alexanndria University, Egypt between1st of September 2018 to the 1st September of 2019. All patients were evaluated by 2D ultrasound for morphological features of the masses combined with colour Doppler examination of their vessels. The final diagnosis, based on histopathological analysis, was used as a gold standard.
Results: Eighty four patients were recruited, 41 with benign masses, 43 with malignant masses. Features that allowed statistically significant discrimination of benignity from malignancy were; wall thickness, presence and height of the largest papillary projections septation, Echogenicity, largest diameter of the solid component, colour score ,Doppler indices; RI cutoff
