Irregular Gestational Sac

What Is

Irregular Gestational Sac?

An irregular gestational sac is the sac of fluid in which an embryo develops in very early pregnancy that has irregular or ill-defined borders in comparison to a normal gestational sac.

Gestational sacs can vary in shape to a certain degree, but an irregular gestational sac is usually a cause for concern as they are predictors of poor pregnancy outcomes.

Ultrasounds that show irregular gestational sacs are normally followed up by further ultrasounds or other imaging to confirm the diagnosis and determine the risk of miscarriage.
