Subependymal hemorrhage, which primarily occurs in premature neonates, is divided into four grades. A grade III subependymal hemorrhage corresponds to intraventricular hemorrhage with ventriculomegaly (also referred to as hydrocephalus). A description of the four grades of subependymal hemorrhage is provided in the Table below.
Imaging studies to assess subependymal hemorrhage include CT and MRI. A CT scan taken during the acute phase of subependymal hemorrhage, or an MRI study taken during acute and/or later stages of hemorrhage, help to determine the location and grade of the hemorrhage. CT, which is more commonly used, readily demonstrates acute hemorrhage as hyperdense signal intensity. Multifocal hemorrhages at the frontal, temporal, or occipital poles suggest a traumatic etiology.

|II||Intraventricular hemorrhage without ventriculomegaly|
|III||Intraventricular hemorrhage with ventriculomegaly|
|IV||Intraventricular hemorrhage with parenchymal hemorrhage|
