title: Pediatric Idiopathic Intracranial Hypertension Presenting With Sensorineural Hearing Loss.
abstract: OBJECTIVE
  To present the rare case of a young boy with idiopathic intracranial hypertension presenting with bilateral sensorineural hearing loss developing over several months. This was accompanied by headaches, otalgia, tinnitus, and vertigo. Furthermore, we aim to provide a concise review on this matter, as this report represents the second case in literature of pediatric idiopathic intracranial hypertension presenting with hearing loss.
  
  
  METHODS
  Workup of a 9-year-old boy with bilateral sensorineural hearing loss, including (among others) physical examination, audiometry, diagnostic imaging, and lumbar puncture.
  
  
  RESULTS
  Physical examination including fundoscopy as well as imaging showed no abnormalities. At presentation, pure tone audiometry revealed bone conduction thresholds of about 30 dB HL in both ears. Two months later, this declined to about 35 dB HL in both ears. Lumbar puncture revealed an increased intracranial pressure. The boy was thus diagnosed with idiopathic intracranial hypertension. After the lumbar puncture, the otological complaints gradually resolved, and the hearing normalized (bone conduction thresholds of 0-5 dB HL).
  
  
  CONCLUSIONS
  Although rare, sensorineural hearing loss in the pediatric population together with otalgia, tinnitus, and vertigo can be due to idiopathic intracranial hypertension and as such can be reversible.
