Intraventricular hemorrhage grading, which feature defines Grade 4 IVH?

Grading intraventricular hemorrhage (Papile system) hinges on how far the bleeding spreads. Grade IV is defined by blood in the ventricles that also extends into the brain parenchyma, causing intraparenchymal hemorrhage. This parenchymal involvement distinguishes it from lower grades: IVH without dilation is Grade II, and IVH with ventricular dilation but no parenchymal spread is Grade III. So the defining feature is IVH with intraparenchymal hemorrhage, which also signals more extensive brain injury and a worse prognosis.
