A coronal section through the brain at the level of the caudate nucleus and putamen. The arrow points to hemorrhagic infarction of the putamen and caudate nucleus. The overlying cerebral cortex and white matter is also involved but the hemorrhagic part of a hemorrhagic infarct is usually confined to the grey matter. Note how swollen the affected hemisphere is, with herniation of structures across the midline.
Most hemorrhagic infarcts are due to emboli.
