Necessity of repeat head computed tomography after isolated skull fracture in the pediatric population

Abstract Background Head injuries are common in the pediatric population, but when an isolated skull fracture is found, there are no guidelines for repeat imaging. This study evaluated the need for repeat head computed tomography (CT) for isolated skull fracture. Methods A 10-year retrospective review was conducted of patients 17 years and younger with isolated skull fractures. Data included demographics, injury severity score (ISS), fracture location, clinical indicators of head trauma, intracranial hemorrhage, and mortality. Results Of the 65 patients in this study, mean age was 4.2 years, ISS was 7.2, and head/neck abbreviated injury score was 2.3. Most injuries were from falls (69.2%) and motor vehicle collisions (23.1%). The most common clinical indicators associated with skull fractures were nonfrontal scalp hematoma (40.0%), severe mechanism (30.8%), and loss of consciousness (30.8%). One patient who developed intracranial hemorrhage after the initial head CT showed no bleed. There were no deaths. Conclusion Isolated skull fractures in the pediatric population do not necessitate a repeat head CT as long as they do not develop worsening clinical indicators of head injury.
