Sonographic evaluation of the yolk sac.
This pictorial essay aims to inform related clinicians by summarizing the normal and abnormal sonographic findings of the yolk sac in the first trimester of pregnancy. An abnormality in the sonographic appearance of a yolk sac can predict subsequent embryonic death or abnormalities. Therefore, the accurate recognition of normal and abnormal sonographic findings concerning the yolk sac can be used to anticipate the course of pregnancy.
