Fetal intracerebral hemorrhage in the second trimester: diagnosis by sonography and magnetic resonance imaging.

Germinal matrix intraventricular hemorrhage has rarely been observed in the fetus. In most cases the etiology is clear. We report one case of prenatal diagnosis of a periventricular hemorrhage of uncertain etiology in a fetus of 22 weeks' gestation. For confirmation of the ultrasound diagnosis, antenatal magnetic imaging was performed. A male child was delivered in good condition at 37 weeks by Cesarean section. Postnatal ultrasound examination showed a cystic lesion in the right frontal lobe (10 x 10 mm) connecting with the right lateral ventricle. The development of the child at 18 months of age has been normal without any neurological impairment.
