Basal Ganglia Cerebrovascular Disease
| Definition: |
Infarction, hemorrhage, ischemia, or hypoxia of any component of the BASAL GANGLIA of the brain. Clinical manifestations may include involuntary or dyskinetic movements and hemiparesis (secondary to involvement of the INTERNAL CAPSULE). Etiologies include atherosclerosis, hypertension, inflammatory conditions (e.g., vasculitis), and emboli of arterial or cardiac origin. Lacunar infarctions frequently occur in the basal ganglia. Hemorrhages in this region are associated with hypertension, but may also result from the rupture of vascular malformations. |

Basal Ganglia Hemorrhage - Extravasation of blood into a basal ganglia nucleus (e.g., caudate, globus pallidus, amygdala, putamen, and claustrum). Clinical manifestations may include acute hemiparesis, movement disorders, headache and/or alterations of consciousness. Hypertension and vascular malformations are relatively common causes of this condition. Pathologically, these hemorrhages are associated with lipohyalinosis of small blood vessels and Charcot-Bouchard microaneurysm formation. (Adams et al., Principles of Neurology, 6th ed, p836) |
