The lesions are a mass of fibrin formed secondary to thrombosis. They dissect and form a subchorionic thrombohematoma which ultimately causes stripping of the chorionic plate away from the villous spaces.
- may be seen as a multiloculated, thick subchorionic hematoma
- maybe echogenic or hetroechoic
Treatment and prognosis
Fetal demise may occur if the placental circulation is affected significantly
