Grade	Description
I	Either: Bleeding that is confined to the germinal matrix (ie, GMH only), or GMH plus IVH occupying <10% of the lateral ventricular area
II	IVH that occupies 10 to 50% of the lateral ventricle area
III	IVH that occupies >50% of lateral ventricle area and is associated with acute ventricular dilation
PVHI (previously called grade IV)	Hemorrhagic infarction in periventricular white matter ipsilateral to large IVH
