contusion

 [kon-too´zhun]
injury to tissues with skin discoloration and without breakage of skin; called also bruise. Blood from the broken vessels accumulates in surrounding tissues, producing pain, swelling, and tenderness, and the discoloration is the result of blood seepage just under the skin. Most heal without special treatment, but cold compresses may reduce bleeding if applied immediately after the injury, and thus may reduce swelling, discoloration, and pain.

If a contusion is unusually severe, the injured part should be rested and slightly elevated; later application of heat may hasten absorption of blood. Serious complications may develop in some cases. Normally blood is drawn off from the bruised area in a few days, but occasionally blood clotted in the area may form a cyst or may calcify and require surgical treatment. Contusions may also be complicated by infection.
cerebral contusion contusion of the brain following a head injury. It may occur with extradural or subdural collections of blood, in which case the patient may be left with neurologic defects or epilepsy. (See also cranial hematoma.)
