Abstract

Idiopathic intracranial hypertension (IIH) is a rare diseaseand local epidemiological data on childhood IIH is limited. Presenting symptomsare often nonspecific and may mimic migraine. We report an adolescent with IIHwho did not have classical predisposing risk factors. Annual incidence in HongKong is estimated to be 0.78 per 100,000 paediatric admissions to public hospitals.Enhanced awareness and prompt treatment is important as delayed diagnosis isassociated with high risk of permanent visual damage. Urgent surgical interventionis necessary for those who do not response to medical treatment.
