Objectives: Describe the ultrasound features of benign asymptomatic adnexal masses submitted to surgical excision and prospectively assess the diagnostic performance of simple rules model to predict benignity. Methods: Observational study between January 2013 and December 2017, including asymptomatic women from a tertiary hospital with an adnexal mass diagnosed on a transvaginal grey scale and colour Doppler ultrasound by a skilled sonographer, before surgery. A standardised examination technique and predefined definitions of ultrasound characteristics based on IOTA terminology were used. Women with histological diagnosis of malignancy or presence of endometriotic tissue in the adnexal lesion were excluded. Results: Of the 93 women submitted to surgical excision, 79 (84%) were included in the study. Morphological description of the lesions included: 40 unilocular, 12 multilocular, 11 solid, 8 unilocular solid and 8 multilocular solid. Vascularisation was colour score-1 in 62 cases with no colour score-4 cases. For the cystic lesions (median diameter of 78mm), the cyst content was: anechoic in 27 cases, low-level in 25, mixed in 13 and ground glass in 6 cases. The presence of papillary projections was observed in 6 unilocular solid and 5 multilocular solid lesions, with a maximum of 2 projections, with no vascularisation. For the solid lesions (median dimeter of r 49mm) acoustic shadows, regular contours and colour score-1 were present in all cases. No ascites was described. When using the simple rules, all tumours were classified as benign. Conclusions: The results demonstrate the high diagnostic accuracy of simple rules risk calculation system regarding benign asymptomatic adnexal masses in these population.
