Intracerebral arterial aneurysm in a newborn

Angiographic diagnosis of an intracerebral aneurysm in a neonate was made on the 13th day of life following persistent neurological symptoms that began at birth. Rupture of the aneurysm probably occurred within the first day of life. This unusual condition should be considered in newborn infants with unexplained neurological signs or intracranial hemorrhage.
