A viable, intrauterine fetus with a BPD of 59.4mm and a GA of 24w2d is present, with no obvious gross morphological abnormalities. There is adequate amniotic fluid and the placental morphology appears to be normal.
Intrauterine mass with multiple tiny cystic structures that resembles a snowstorm or a bunch of grapes just distal to the placenta, which appears to be normal. The bulk covered the internal cervical os and filled the anterior lower uterine cavity. The mass had no discernible fetal components, and it clearly separated from the placenta above. By using color Doppler interrogation on the mass, no apparent flow noticed.
