Deep right intracerebral hemorrhage centered on the thalamus.  Its location and background brain features are in keeping with a "hypertensive" (arteriolosclerosis) hemorrhage.

PATHOLOGY

The patient died the same day as the ICH and underwent post mortem.  This showed an extensive right sided cerebral hemorrhage centered in the thalamus and extending into the ventricular system, which is distended.

Throughout the cerebral and cerebellar white matter there is small vessel disease in the form of lipohyalinosis and arteriolosclerosis. Immunohistochemistry shows no significant vascular amyloid.
