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

The patient underwent a post-mortem which showed an old left thalamic hematoma. There was extensive small vessel disease with enlarged perivascular spaces, white matter rarefaction, and small lacunar infartcs. There was no significant amyloid angiopathy.
