Deep left intracerebral hemorrhage centered on the basal ganglia/external capsule.  Its location and background brain features are in keeping with a "hypertensive" (arteriolosclerosis) hemorrhage.

PATHOLOGY

The patient died 9 months after the ICH and underwent a post mortem.  This showed an old hematoma in the left basal ganglia, extending to the insular cortex laterally and lateral ventricle medially.

There is severe small vessel disease throughout the cerebral hemispheres.  Immunohistochemistry shows only occasional meningeal and parenchymal amyloid angiopathy.
