hematoma

n. an abnormal accumulation of blood as a result of vessel leakage or rupture. In the brain, hematomas can cause substantial behavioral deficits, and even death, by increasing intracranial pressure. Although some may spontaneously reabsorb and disappear, others must be surgically evacuated. See epidural hematoma; subdural hematoma.
