Intraventricular hemorrhage is bleeding in the ventricles of the brain, most often seen in infants born after less than 31 weeks of gestation. The most common site (over 60% of the time) is the subependymal germinal matrix, which is a primitive cellular region located ventrolateral to the lateral ventricle at the level of the foramen of Monro. Diagnosis is confirmed by real-time ultrasound.
