Also called a hemorrhagic stroke, it is a haemorrhage or bleeding into the substance of the cerebrum, usually in one hemisphere and in the region of the internal capsule through the rupture of the lenticulostriate artery (one of the branches of the middle artery that supply structures in the basal ganglia where most hemorrhages due to ruptured microaneurysms occur). It can happen as a consequence of very preterm delivery, and constitutes a risk for cerebral palsy.
