In spontaneous hypertensive intracerebral haemorrhage, the most common site of bleeding is:
- A Putamen and adjacent internal capsule ✓
- B Cerebellar hemisphere
- C Pons
- D Lobar subcortical white matter
Correct answer: A. Putamen and adjacent internal capsule
Explanation
Chronic hypertension produces lipohyalinosis and Charcot-Bouchard microaneurysms of deep penetrating arteries (lenticulostriate branches), making the putamen and internal capsule the single most common site, followed by thalamus, pons and cerebellum. Lobar haemorrhage points instead toward cerebral amyloid angiopathy in the elderly, a different mechanism from deep perforator disease.
