Core Tip
Core tip: Placental necrosis with extremely high maternal serum α-fetoprotein (AFP) is rare. We reported a 23-year-old female patient with central placenta previa suffered from repeated vaginal bleeding. Follow-up ultrasonography revealed a gradually enlarging hypoecho between the amniotic sac and the uterine myometrium. Until 32 wk of gestation, laboratory results showed extremely elevated maternal serum AFP. Both intraoperative exploration of the placenta and histological examination demonstrated the hypoechoic area was necrotic tissue. To our knowledge, this is the first report of a rare case of extreme AFP level in placental necrosis. Clinicians should consider the combination usage of quantitative ultrasound imaging and AFP as a practical tool for assessing placental lesions.
