[Idiopathic intracranial hypertension. Review of our experience in the last eight years (2016-2023)].

INTRODUCTION

Idiopathic intracranial hypertension (IIH) or benign intracranial hypertension is a rare disease in childhood. The clinical presentation in pediatric patients can be very variable, being more unespecific in younger patients.

PATIENTS AND

METHODS

A retrospective descriptive study was carried out on patients diagnosed of IIH in the last eight years (2016-2023) in the neuropediatrics unit of a tertiary hospital. In the present study, the clinical-epidemiological characteristics and the diagnostic-therapeutic procedure carried out in each case were analyzed.

RESULTS

We studied 14 patients, 57% were women. The average age at diagnosis was 9 years, headache was the most common reason for consultation. In all patients, papilledema was found in the fundus and neuroimaging didn´t find alterations. Optical coherence tomography has been carried out in 78.5% of the sample, > 80% of patients showed thickening of the retinal nerve fiber layer. All patients had a high cerebrospinal fluid opening pressure (>25 cmH2O). 57% of patients required treatment with acetazolamide, a carbonic anhydrase inhibito. In all patients the resolution was complete, however almost 30% of them have presented recurrences during follow-up.

CONCLUSIONS

In recent years there has been an increase in the incidence of this entity, making early diagnosis and treatment essential to avoid possible irreversible damage.
