In spontaneous intracerebral haemorrhage secondary to chronic hypertension, which anatomical site is affected most frequently?
- A Putamen ✓
- B Cerebellar vermis
- C Frontal lobe white matter
- D Pons tegmentum
Correct answer: A. Putamen
Explanation
The putamen and adjacent internal capsule account for roughly half of hypertensive intracerebral haemorrhages, supplied by lenticulostriate arteries prone to Charcot-Bouchard microaneurysms. Thalamus, pons, and cerebellum follow in frequency. Lobar haemorrhage in an elderly patient points instead toward cerebral amyloid angiopathy rather than chronic hypertension, which is the discriminating fact against option C.
