A 14-week pregnant woman had a mixed echogenic mass of size 4x12 cm at placenta portion
and normal fetus at ultrasound. The image of the mass was very similar to a huge subchorionic
hematoma (SCH). The fetal chromosomes by amniocentesis were normal. The presumed diagnoses
were huge SCH or twin pregnancy with complete hydatidiform mole and co-existent fetus
(CHMCF). A male fetus weighing 760 g was delivered at 25 gestational weeks. The findings
on the placental biopsy showed twin pregnancy with CHCMF. With ultrasound findings
of this type, the possibility of a huge SCH and twin pregnancy with CHMCF should be
considered.
