Intraventricular haemorrhage due to birth injury

**Definition:** Traumatic haemorrhage into the intraventricular space as the dominant lesion, usually in a term infant, a result of birth trauma. Usually seen in conjunction with other intracranial bleeding (parenchymal, subdural, subarachnoid) and can be seen in the term or preterm infant.

**Long definition:** Traumatic haemorrhage into the intraventricular space usually arises from the choroids plexus in the term infant and in the germinal matrix in the preterm infant. In premature infants <30 weeks gestation the incidence of hemorrhage is 30-40%. Intraventricular haemorrhage can be graded on a I-IV scale. Intraventricular haemorrhage is usually seen in conjunction with other intracranial bleeding (parenchymal, subdural, subarachnoid).
