Presentation
Presented to the emergency department with cramping and vaginal bleeding.
Patient Data
Fetus without cardiac activity seen. Non-viable embryo floats in amniotic fluid with no movement tied by chorioamniotic cord. Echogenicity seen centrally.
Case Discussion
Transvaginal ultrasonography was performed initially and showed a fetal pole with a crown-to-rump length consistent with a gestational age of approximately 9 weeks. The fetus in a missed miscarriage shows decreased size as a result of disintegration, lysis and loss of fluid content. Even intrafetal intravascular intracardiac gas is present, which presents as echogenic foci.
