A cerebral contusion is a lesion of the brain, following a traumatic brain injury. After the shock, the individual may lose consciousness for a period of time, or show neurological symptoms such as sensory or motor disturbances, indicative of brain lesions. Contusion owes these symptoms to the fact that it normally accompanies the formation of cerebral edema, meaning an accumulation of liquid in the tissues. The symptoms differ according to which zone of the brain is affected, and these sometimes appear several hours or days after the trauma, the time that the edema takes to form. A brain scan may be done in case of doubt, and the clinical signs generally disappear after several days. In other cases, the evolution can be more troublesome, with the worsening of symptoms indicative of a complication.
