Original Article Intracranial Hypertension in Children: Etiologies, Clinical Features, and Outcome

This retrospective study aimed to describe the clinical presentations, possible causes, and outcomes of children with idiopathic intracranial hypertension who presented to the authors ’ clinic. The mean age at onset of symptoms in the authors ’ cohort of 19 children was 6 years (range: 7 months to 12 years). Most patients (90%) were under 11 years old and (84.2%) symptomatic. The probable cause was identified in 7/19 (37.0%) patients. The most common cause was vitamin D deficiency (26.3%). Other associated probably coincidental comorbidities included sinusitis (5/19, 26.3%), hypophosphatasia (1/19), Pyle disease (1/19), and measles vaccine (1/19). Apart from 2 patients who required lumboperitoneal shunt, the cerebrospinal fluid pressure returned to normal in all patients within a period of 6 weeks to 1 year (average, 5 months). Of those who followed up with the authors’ ophthalmologist, 30.7 % developed optic atrophy or pallor; 75 % of these patients had previous ocular comorbidities
