Aneurysm
Hemorrhage:
Almost 90% of patients who experience a cerebral hemorrhage have a past
history of high blood pressure (hypertension). There is a greater risk
of hemorrhage in certain areas of the brain: the basal ganglia, thalamus,
cerebellum and the pons. The most common pathological mechanism for hemorrhage
is the presence of an aneurysm, or weakening of the arterial wall. This
aneurysm ruptures and hemorrhage results. Hemorrhages produce damage by
mass effect, infarction, and direct destruction of nervous tissue by blood.
