Intraamniotic hemorrhage: challenges in prenatal detection: a case report.

Background: Subamniotic hemorrhage, a rare condition involving bleeding between the amniotic membrane and fetal chorionic plate, presents diagnostic challenges.

Case Presentation: A 35-year-old woman at 37 weeks of gestation who presented with lower abdominal discomfort and decreased fetal movements came to our emergency department. Ultrasound revealed medium-strong echoes in the amniotic fluid and inhomogeneous echoes around the umbilical cord. A Category II fetal heart rate baseline (FHR) tracing, indicative of fetal compromise, along with an elevated MCA-PSV approaching the diagnostic threshold for fetal anemia, suggested ongoing fetal hypoxia or hemorrhage and warranted immediate delivery to mitigate the risk of adverse outcomes. An emergency cesarean section revealed significant intraamniotic hemorrhage and a subamniotic hematoma near the umbilical cord insertion.

Conclusions: This case highlights the importance of considering rare etiologies for common symptoms and underscores the value of timely ultrasonography and decisive intervention in preventing adverse fetal outcomes.
