J Child Neurol. 2021 Oct;36(12):1103-1110. doi: 10.1177/08830738211045234. Epub 2021 Nov 8.

Abstract

A cutoff value of 6.0 mm for optic nerve sheath dilation may be used as a screening imaging marker to suspect elevated opening pressure with specificity of 88% in pediatric patients with new-onset idiopathic seizures.

Keywords: idiopathic intracranial hypertension; intracranial hypertension; pediatric; pseudotumor cerebri; seizure.
