The exact etiology is unknown, but the final pathophysiology is likely to rupture of a spiral artery with hemorrhage into the decidua basalis leading to separation of the placenta. The findings exhibit increased presence of edema, necrosis, polymorphonuclears, deesprendimiento, infarcts, syncytial knots, stromal fibrosis, changes and inflammation of the vessel wall which were increased in placentae of hypertense pacients.

Acute hematomas imaged at the time of symptoms tend to be hyperechoic or isoechoic compared to the adjacent placenta.
Hemorrhage due to abruption appears as an area of medium to high signal intensity on T1 and high signal intensity on a T2 weighted image, located between the placenta and uterine wall.
