Diagnostic and prognostic implications of computed tomography of head trauma

A total of 210 cases of head trauma were examined using noncontrast enhanced and contrast enhanced computed tomography scans. Evidence of contrast enhancement was seen in 97 cases (46%). Subdural hematoma and focal contusion were the most frequent entities demonstrating contrast enhancement. This finding was also frequently seen in patients with intraventricular hemorrhage (IVH) (5 of 17). Every one of the five patients in this series with IVH whose scans showed enhancement died, whereas out of the 12 whose scans showed no enhancement, five survived. Illustrative cases are presented. The authors feel that contrast enhanced scans are valuable in the evaluation of the full extent of head trauma.
