empty gestational sac

Empty gestational sacs can be due to a number of causes:

• anembryonic pregnancy (also known as "blighted ovum")
• early pregnancy (intrauterine): by 5.5 weeks gestational age, a yolk sac should be identifiable by transvaginal ultrasound
• pseudogestational sac with an ectopic pregnancy
• gestational trophoblastic disease: some first trimester moles may mimic an anembryonic pregnancy; correlation with beta hCG levels is helpful
