Arms and outcomes
Arms (3)
- label
- First arm (primary objective):
- description
- First arm (primary objective): Adnexal mass scanned at 11-14 weeks. If the decision is to manage the adnexal mass conservatively, the patient is to be re-scanned once more: 0 - 90 days postpartum. In addition, the patient will be asked to enter into the third arm of the study (see below) knowing that she can opt out from that arm at any point. If she consents to participate in the third arm, she will participate in a series of longitudinal examinations as described for the third arm. All patients with a mass detected before 11 weeks will also be scanned at 11-14 weeks and can enter all three arms of the study. In this scenario, if more than one scan is performed during pregnancy before 11 weeks, only the first of several scans before 11 weeks will be included for the second and third arms of the study.
- interventionNames
- Diagnostic Test: Ultrasound
- label
- Second arm (secondary objective):
- description
- Second arm (secondary objective): Adnexal mass is seen for the first time during that pregnancy at any gestation. If the decision is to manage the adnexal mass conservatively, the patient is to be re-scanned once more: 0 - 90 days postpartum. For patients with a mass detected before 11 weeks, see also above (they will be re-scanned at both 11-14 weeks and at 0-90 days postpartum). In addition, the patient will be asked to enter into the third arm of the study knowing that she can opt out from that arm at any point. If she consents to this, she will participate in a series of longitudinal examinations as described for the third arm.

Inclusion Criteria: * • Consecutive patients with non-physiological adnexal masses or physiological cysts measuring 5cm or more in largest dimension; * In case of more than one mass seen, only most suspicious mass to be included OR in case of two similar masses, the one with the largest dimension or most easily accessible with ultrasound; * Previously recruited patient presenting with a different mass in subsequent pregnancy; * Age 18 years and above. Exclusion Criteria: * • Cysts deemed to be clearly physiological WHEN smaller than 5 cm (largest diameter); * Non-adnexal masses, e.g. peritoneal inclusion cysts (when diagnosis is certain) and peritoneal carcinomatosis with no adnexal mass; * The denial or withdrawal of written informed consent; * Same cyst already recruited for p-IOTA in a previous pregnancy. * Age \< 18 years
