| Bleeding
within the substance of the brain. There may be many causes.
In the absence of trauma, tumors may bleed and cause hemorrhage.
Aneurysms and arteriovenous malformations do as well, although much
of the hemorrhage tends to be in the subarachnoid space.
Hypertension is known to cause hemorrhages in the basal ganglia, brainstem
and cerebellum. Anticoagulation makes the entire brain more
susceptible to hemorrhage. Amyloid angiopathy, also known as
congophilic angiopathy, may cause hemorrhage in the brain in older
patients. |
