Cerebral hemorrhage!
This image shows a freshly removed brain with an intracerebral hemorrhage, take a look at the acute accumulation of blood on the parenchyma of the brain section below. This type of bleed occurs when blood suddenly bursts into or within brain tissue, usually from hypertensive vasculopathy resulting in the rupture of small, penetrating arteries, causing extensive damage. Hypertensive angiopathy stiffens vessel walls and makes them fragile, eventually to swell and bulge.The formation of aneurysms as a result of the chronic hypertension is the reason they may rupture and bleed within the lobes or the deep brain structures.It typically present with sudden focal neurologic deficit that gradually worsen over minutes to hours. The blood clot is surrounded by a zone of compressed ischemic tissue. Vascular leakage, in this zone, causes cerebral edema, which increases over a few days. Thus, the hemorrhage causes focal neurological deficits and, more important, increased intracranial pressure.
