title: Massive subchorionic hematoma: peculiar prenatal images and review of the literature.
abstract: Massive subchorionic hematoma is a localized collection of blood or hematoma in the placenta, and can result in serious obstetrical complications. The condition can be diagnosed antenatally by ultrasound. However, no reports have previously described the same condition featuring an intraplacental fluid-fluid level on imaging studies. We report a case of massive subchorionic hematoma diagnosed prenatally, and propose an additional peculiar finding detectable on both the ultrasound and magnetic resonance images: the intraplacental fluid-fluid level. We also review previously reported cases that were detected by ultrasonography.
