Presentation
Acute right hemiparesis
Patient Data
Non-contrast CT of the brain demonstrates an acute intracerebral haemorrhage centred in the basal ganglia of the left hemisphere. There is extension into the left lateral ventricle (intraventricular haemorrhage), with blood-forming a cast of the lateral ventricle, and passing into the third ventricle. There is no hydrocephalus at this stage.
This diagram depicts the Charcot Bouchard microaneurysms arising from perforating lenticulostriate arteries. These aneurysms typically arise from arteries no larger than 300 micrometres in diameter.

Case Discussion
This type of bleed is characteristic of a basal ganglia haemorrhage secondary to hypertension.
