Masses in Young Patients - International Ovarian Tumour Analysis (MY-IOTA)

"A standardised transabdominal examination is performed, including color or power Doppler examination. Transvaginal ultrasonography can be performed in sexually active adolescents with consent. Transrectal examination is also acceptable for younger patients who are not sexually active. All the variables required for the Simple Rules, simple descriptors and ADNEX model are assessed.~Before entering ultrasound information about the tumour and getting model results, the ultrasound examiner' s diagnosis (benign, borderline, malignant; specific diagnosis) based on subjective assessment is recorded. Results based on Simple Rules, simple descriptors and ADNEX model are documented as well.~If the adnexal mass is seen and if the decision is to manage the adnexal mass conservatively, the patient will be re-scanned at 6 weeks (maximal range 6-8 weeks), 3 months (+/- 2 weeks) and 12 months (maximal range 10-14 months)"
