Occipital Headaches and Neuroimaging in Children (P4.324)
Neurology recent issues
OBJECTIVE:To determine the implications of occipital headache in children and clarify when imaging is indicated.BACKGROUND:Occipital headache in children is considered a warning sign of intracranial pathology. The new ICHD-3 beta criteria for migraine state, "Occipital headache in children is rare and calls for diagnostic caution." Support for this comes from studies in emergency departments rather than neurologists' offices.DESIGN/METHODS:We performed a retrospective chart review cohort study of all patients referred to a child neurology clinic for headache in 2009. Patients were stratified by headache location: solely occipital, occipital plus other area(s) of head pain, or no occipital involvement. We assessed location as a predictor of 1) whether neuroimaging was ordered, and 2) whether intracranial pathology was found. Analyses were performed using logistic regression, Chi-Square, and Fisher's exact tests.RESULTS:A total of 356 patients were included. Median age was 12.1 years (27 months to 18 years), and 56.5% were female. Headaches were solely occipital in 6.4% and occipital-plus in 13.2%. Patients with occipital head pain were more likely to undergo neuroimaging than those without occipital involvement (solely occipital: 91%, RR 4.9, 95% CI 1.2-20.6; occipital-plus: 85%, RR 2.7, 95% CI 1.2-5.8; no occipital pain: 65%, ref.). Occipital pain alone or with other locations was not significantly associated with radiographic evidence of elevated intracranial pressure, tumor, benign cyst, or sinusitis. Occipital pain was associated with Chiari I malformation (solely occipital: RR 4, 95% CI 1.2-13.5; occipital-plus: RR 3.3, 95% CI 1.5-6.9).CONCLUSIONS:Children with occipital headache are more likely to undergo neuroimaging. In our study, occipital pain was associated with Chiari I malformation but not with more serious intracranial pathology. Detecting a Chiari I malformation is useful only if the clinical presentation is consistent with tonsillar compression; otherwise, it may be an incidental finding in a child with migraine. Without a worrying history and with a normal examination, neuroimaging can be deferred in most pediatric patients when occipital pain is present.
