Abstract

Subamniotic hematoms are rare placental pathological lesions resulting from the rupture of chorionic vessels near the cord insertion. Most subamniotic hematomas are found after birth and result from excessive traction on the umbilical cord at delivery. The development of these lesions has been rarely reported in utero. A case of a subamniotic hematoma was diagnosed by ultrasound at 7(+5) weeks of gestation. We describe the ultrasound features of a subamniotic hematoma and the differential diagnosis.
