Prenatal sonographic diagnosis of fetal intracranial hemorrhage

Objective To investigate the diagnostic value of prenatal ultrasonography in the fetal intracranial hemorrhage.Methods In a retrospective analysis,the ultrasonographic findings of five fetuses with intracranial hemorrhage diagnosed in our hospital were reviewed and compared with other imagemodalities.Results In the five fetuses with intracranial hemorrhage,the ultrasonographic features mainly included dilated uni-or bilateral ventricles and intraventricular echogenic foci or periventricular echodensities.The diagnosis of all cases were confirmed by prenatal magnetic resonance.Four of these cases chose termination of pregnancy,and the other fetus had a normal neurological follow-up after birth.Conclusions Fetal intracranial hemorrhage can be diagnosed accurately by prenatal ultrasonography,especially in the second and third trimester.It is rarely associated with other anomalies.Prenatal sonographic examination may detect the lesion and help to evaluate the prognosis.
