Pediatric intracranial hypertension: A review of presenting symptoms, quality of life, and secondary causes

Abstract

AbstractOur understanding of primary (idiopathic) intracranial hypertension has evolved in recent years. There have been efforts to rename the disorder as pseudotumor cerebri syndrome or primary intracranial hypertension. Some studies have suggested a higher threshold opening pressure to define intracranial hypertension. The reported annual incidence varies from 0.6 to 0.9 per 100 000 children around the world. Patients are typically divided into prepubertal and pubertal groups, with pubertal patients having the same risk factors as adults. Prepubertal patients do not share these risk factors. They are more likely to be asymptomatic, have equal gender distributions, and are less likely to be obese. Headache is the most common presenting complaint, followed by vision changes and nausea/vomiting. A newer concept of fulminant intracranial hypertension has emerged, defined as acute onset with rapid progression of visual deficits or papilledema. Quick insertion of a temporary lumbar drain as a bridge while medical management reaches effectiveness improves visual outcomes and helps avoid permanent shunt placement. Headache is typically the first symptom to resolve with treatment, and papilledema resolves in five to six months. Recurrence rates in children and adolescents range from 28.5% to 36.4%, with higher rates after puberty.
