A Breus mole is a term that was given to a very large subchorionic haemorrhage.
The lesions are a mass of fibrin formed secondary to thrombosis. They dissect and form a subchorionic thrombohematoma which ultimately causes stripping of the choriconic plate away from the villous spaces.
- may be seen as a multiloculated, thick subchorionic haematoma
- may be echogenic or hetroechoic
Fetal demise may occur if the placental circulation is affected significantly
