Cranial computed tomography in diagnosis and management of acute head trauma.

Review of the computed tomographic findings in 286 patients with acute craniocerebral trauma revealed several types of lesions: hemorrhagic contusion, intracerebral and extracerebral hematomas, general and focal cerebral swelling, and shearing injury of the cerebral white matter. Hemorrhagic contusions are the most frequent lesion and may result in focal neurologic deficits. General cerebral swelling occurs frequently in children and necessitates prompt medical management for complete recovery. Mortality rates for intracerebral, subdural, and epidural hematomas were lower for this series than for series that preceded computed tomography. Because of the availability of computed tomography, there was an 84% reduction in arteriography, 58% reduction in surgical intervention, and a 24% reduction in skull radiography.
