What term denotes the fluid filled sac structure normally found in the uterus, containing pregnancy?

• A. Gestational Sac
• B. Gestational Age
• C. Empty Amnion Sign
• D. Embryo

Answer: (A)

The fluid-filled sac within the uterus that marks the presence of pregnancy is the gestational sac. It appears on ultrasound as a round or oval dark space surrounded by a brighter rim, located inside the endometrium. This sac is the first clear sign of an intrauterine pregnancy and may contain the yolk sac and, later, the developing embryo. Remember, gestational age is a measure of how far along the pregnancy is, not a structure. The empty amnion sign is a separate ultrasound finding and not the sac that contains the pregnancy. The embryo is the developing baby inside the sac, not the sac itself.
