title: Idiopathic intracranial hypertension in pediatric population: case series from India.
abstract: BACKGROUND
  Idiopathic intracranial hypertension (IIH) is a well described entity in adults. In pediatric age group the presentation of disease can vary depending on the age of patients and is less frequently reported.
  
  
  OBJECTIVE
  The aim of this study is to describe the clinical features, investigations, treatment and outcome of IIH in pediatric population (age <18 years).
  
  
  METHODS
  This retrospective hospital based study was carried out on 25 children with diagnosis of IIH based on modified Dandys criteria. Their clinical, investigation, treatment, outcome and follow-up for 2 year period were analyzed.
  
  
  RESULTS
  Out of the 25 children, the youngest child was 4-month-old infant. The commonest symptom was headache (76%) followed by vomiting and papilledema (72%). The mean cerebrospinal fluid (CSF) pressure was 330 mm of H 2 O. In Infants irritability and bulging anterior fontanelle was seen. A total of 24 patients showed a complete resolution of symptom. None of patient had recurrence over a period of 2 years follow-up.
  
  
  CONCLUSIONS
  IIH can present at any age group. This is the largest series of IIH reported in pediatric population in India. The clinical features are similar to adult patients except in infants. Absence of papilledema does not exclude the diagnosis of IIH. CSF pressure monitoring is needed in suspected cases of IIH. Early and prompt treatment can prevent deficits.
