Pediatric Idiopathic Intracranial Hypertension Post-Measles Vaccine: A Case Report

Idiopathic intracranial hypertension is characterized by an increase in intracranial pressure with no significant structural cause. The diagnostic criteria include general signs and symptoms of generalized increased intracranial pressure or papilledema, increased Cerebrospinal Fluid (CSF) pressure (>250 mm H2O), and normal brain imaging. It usually occurs in adults but rarely can be seen in children. We report a 7-year-old child with a manifestation of increased intracranial tension after the measles vaccine, associated with bilateral sixth nerve palsy and bilateral facial palsy with lower motor neuron features. Normal magnetic resonance imaging and CSF results were normal, except for an increase in CSF pressure. The symptoms began to be resolved after lumbar puncture with the complete resolution of symptoms after one and half months. We add also acetazolamide at the proper dose to reduce intracranial pressure from the first day of diagnosis.
