Can a cerebral contusion have any complications?

Dr. Jeanne Morrison, PhD
Family Practitioner

Cerebral contusions (a bruise on the brain) are a type of traumatic brain injury (TBI). Mild injuries of this type sometimes go unnoticed with no lasting damage. More severe injuries can cause permanent damage, coma, or even death. About two percent of individuals with TBI in the United States will require long-term or full-time care. Cerebral contusions result when a blow to the head causes the brain to hit the hard bone of the skull, bruising the brain. Because the swelling has nowhere to go inside the skull, it presses on the brain causing structural damage. Complications include other injuries that go unnoticed, fever, seizures, high blood pressure, low oxygen levels, and loss of memory.
