CT scan of the brain of a 6 month old child showing a subdural hematoma. This child was suspected of being a victim of child abuse, and having suffered "shaken baby syndrome". A subdural hematoma is a traumatic brain injury in which blood accumulates within the inner meningeal layer of the dura matter. They usually result from tears in veins that cross the subdural space. In contrast, epidural hematomas are usually caused by tears in arteries, resulting in a buildup of blood between the dura and the skull. Subdural hematomas are usually the result of a traumatic head injury, when fast changing velocities within the skull may stretch and tear small bridging veins. Subdural hemorrhage is a classic finding in shaken baby syndrome. Subdural hematoma is also commonly seen in the elderly and in alcoholics, who have evidence of cerebral atrophy. Cerebral atrophy increases the length the bridging veins have to traverse between the two meningeal layers, hence increasing the likelihood of s
