You are seeing a patient referred by her primary care provider for consultation at your tertiary center’s high-risk obstetrics unit. She is a 37-year-old primigravida currently at 13+2 weeks’ gestation with an incidental 7-cm complex right adnexal mass detected last week on routine first-trimester sonography performed at an external center. Although the ultrasound report is not yet available to you, the consultation note confirms a singleton intrauterine pregnancy with normal fetal morphology and low risk of aneuploidy using sonographic markers. Routine serum prenatal investigations are only significant for iron-deficiency anemia.
