Ultrasound in congenital intracranial haemorrhage secondary to isoimmune thrombocytopaenia.

Three cases of congenital intracranial haemorrhage, diagnosed post-natally by ultrasound, are presented. The ultrasound findings of intracranial haemorrhage secondary to thrombocytopaenia are discussed. The haematomas were partly organised at birth and the ventricular systems were dilated in two cases. This type of haemorrhage is a different entity from post-natal intracranial haemorrhage in the preterm infant.
