Breus mole

Dr Mohamed Saber and Radswiki et al.

A Breus mole is a term that was given to a very large subchorionic hemorrhage, an unfortunate misnomer because this entity bears no relationship to the molar pregnancy.

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

Fetal demise may occur if the placental circulation is affected significantly

It was first described by Carl Breus, an Austrian obstetrician, in 1892 2.
