ACR Appropriateness Criteria® on Headache-Child

In a pediatric patient with an isolated headache or a classic migraine unaccompanied by neurologic signs, presence of a seizure, or supporting historical data, an imaging workup is usually not indicated. For a sudden severe headache or a headache with positive neurologic signs or symptoms or supporting historical data, MRI or CT should be considered. For the acute severe (thunderclap) headache, CTA, MRA, or catheter angiography may be appropriate.
