Spontaneous intraventricular haemorrhage in utero.

The authors report three cases of unexplained prenatal intraventricular haemorrhage (IVH) in three term infants. In the first two cases the suspected diagnosis of prenatal IVH was made a few hours after delivery, in accordance with the ultrasonographic feature of clots in the ventricles, whereas in the third case prenatal ultrasonography was suggestive of hydrocephalus with intraventricular clots.
