Which of the following is the commonest location of hypertensive haemorrhage –
**Core Concept**
Hypertensive hemorrhage typically occurs in the setting of chronic hypertension, where small, fragile vessels in the brain are damaged, leading to the formation of a hemorrhage. The most common location of hypertensive hemorrhage is in the basal ganglia, thalamus, or cerebellum, which are areas supplied by small, perforating arteries that are prone to damage.
**Why the Correct Answer is Right**
The correct answer is **B. Basal ganglia**. The basal ganglia are a collection of structures in the brain that are involved in movement control and cognition. They are supplied by small, perforating arteries that arise from the lenticulostriate arteries, which are prone to damage in the setting of chronic hypertension. The damage to these small vessels can lead to the formation of a hemorrhage in the basal ganglia, which is the most common location of hypertensive hemorrhage.
**Why Each Wrong Option is Incorrect**
* **Option A:** The cerebral cortex is not a common location for hypertensive hemorrhage, as it is supplied by larger arteries that are less prone to damage from chronic hypertension.
* **Option C:** The pons and medulla are areas of the brainstem that are also prone to hemorrhage, but they are less common locations for hypertensive hemorrhage compared to the basal ganglia.
* **Option D:** The cerebellum is a common location for hypertensive hemorrhage, but it is not the most common location, which is the basal ganglia.
**Clinical Pearl / High-Yield Fact**
Hypertensive hemorrhage is often referred to as a "putaminal hemorrhage" when it occurs in the basal ganglia, as the putamen is a structure within the basal ganglia that is commonly affected. This type of hemorrhage is often associated with a poor prognosis and a high mortality rate.
**Correct Answer:** B. Basal ganglia
