Haemorrhagic stroke, animation
Animation of a sagittal view of a brain with a haemorrhagic (bleeding) lesion (coloured) in the putamen of the left basal ganglia. The bleed is consistent with a hypertensive intracerebral haemorrhage, a haemorrhagic stroke caused by high blood pressure (hypertension). In this type of stroke the putamen often sustains damage when the lenticulostriate arteries supplying the basal ganglia rupture due to chronic hypertension or small vessel disease. Positioned near the internal capsule, this bleed could potentially impair corticospinal pathways, leading to right-sided weakness (hemiplegia). When the left hemisphere is dominant for language, additional language deficits such as aphasia may occur. Despite the pronounced haemorrhage, there is no clear midline shift, suggesting a limited mass effect at this stage.
