Intra-parenchymal cerebral hemorrhage! Take a look at the acute accumulation of blood on the parenchyma of the brain sections above. These type of brain hemorrhages typically present with sudden focal neurologic deficit that gradually worsen over minutes to hours. Hypertensive vasculopathy involving the small penetrating branches of the major cerebral arteries is the most common cause of spontaneous deep intracerebral bleeding. This is due to the formation of aneurysms as a result of chronic hypertension, which may rupture and bleed within the lobes or the deep brain structures.
