We describe a case of hepatic hemangioendothelioma that was first suspected
based on prenatal sonographic findings at 19 weeks' menstrual age. At 16 w
eeks, the patient presented with a markedly elevated maternal serum alpha-f
etoprotein level. Serial sonographic examinations revealed that the fetus h
ad cardiomegaly, hepatomegaly with a hepatic mass and dilated intrahepatic
vessels, a single umbilical artery, and a placental chorioangioma. Arteriov
enous shunting within the hepatic mass was seen using color Doppler and pul
sed Doppler sonography. An enlarged artery arising from the abdominal aorta
supplying the mass was demonstrated. Postnatal physical examination and ra
diologic studies supported the diagnosis of hepatic hemangioendothelioma. T
he evolution in the sonographic appearance of this hepatic lesion in utero
over a 17-week period is described. (C) 2000 John Wiley & Sons, Inc.
