Patient Data

Age: 90 years
Gender: Female

Left sided acute intracerebral hematoma, with its epicenter in the basal ganglia/external capsule. The hemorrhage extends into the intraventricular system.  There is no subarachnoid hemorrhage.

There is no hydrocephalus or significant mass effect relating to the hematoma.

Mild generalized cerebral volume loss. Mild periventricular low attenuation in keeping with small vessel change. There are a couple of chronic lacunar infarcts in the basal ganglia

Case Discussion

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.



The patient died 4 months after the ICH and underwent post mortem.  This showed an old left basal ganglia hemorrhage.

There is severe small vessel disease throughout the cerebral hemispheres with lacunar infarcts, enlarged perivascular spaces and white matter rarefaction. Immunohistochemistry shows parenchymal amyloid deposition in keeping with Alzheimer's pathology but no evidence of amyloid angiopathy.
