چکیده (انگلیسی):

The majority of cases of placenta accreta are unanticipated and initially identified intraoperatively.
Although color Doppler ultrasound is adequate for the evaluation of placenta
accreta in the third trimester, ultrasound diagnosis in the first trimester has never been
reported. To our knowledge, this is the first case of placenta accreta detected at 9 weeks'
gestation by ultrasound. Placenta accreta with intraplacental lacunae can be identified
together with a loss of the hypoechogenic retroplacental myometrial zone. Based on this
case, we found that early diagnosis of placenta accreta in the first trimester by ultrasound
is possible.
