Answer

In hemorrhagic stroke, bleeding occurs directly into the brain parenchyma. The usual mechanism is thought to be leakage from small intracerebral arteries damaged by chronic hypertension. The terms intracerebral hemorrhage and hemorrhagic stroke are used interchangeably in this article and are regarded as separate entities from hemorrhagic transformation of ischemic stroke. See the image below.

Axial noncontrast computed tomography scan of the Axial noncontrast computed tomography scan of the brain of a 60-year-old man with a history of acute onset of left-sided weakness. Two areas of intracerebral hemorrhage are seen in the right lentiform nucleus, with surrounding edema and effacement of the adjacent cortical sulci and right sylvian fissure. Mass effect is present upon the frontal horn of the right lateral ventricle, with intraventricular extension of the hemorrhage.
