Introduction: The Pseudotumor cerebri syndrome may be primary (idiopathic intracranial hypertension) or secondary cause. It is important to recognize that patients with a secondary cause and papilledema may be indistinguishable from those with IIH. In addition to addverssing the secondary cause, these patients frequently require treatments used for IIH in order to prevent blindness.

Objective: Describe a group of patients with diagnosis of benign intracranial hypertension and the associated conditions  which can define an idiopathic intracranial hypertension or secondary psedudotumor cerebri in this entity.

Materials y methods: Retrospective analysis of clinical charts. All patients 18 years old or younger between March 2005 and March 2013 with benign intracranial hypertension who met Dandy Modified Criteria were included..

Results: 16 patients were included (6 female). Headache (14/16), diplopia (4/16) and tinnitus 3/16) were the morefrequent symptoms reported. Associated conditions were present in ten patients (62,5%) : LLA preB (2/16), drugs (6/16), morbid obesity (1/16), renal failure (1/16). No associated conditions were found in 6 patients. Just one patient presented recidivisms. Only one patient loss visual acuteness.

Conclusion: HII in infancy is a diagnosis of exclusion.In our experience, En  62,5% of children had associated conditions.In pediatric population with HII a complete evaluation is suggest so associated conditions can be exclude.
