Abstract
BACKGROUND: Idiopathic intracranial hypertension is a rare neurological disorder of unknown etiology. It is characterized by symptoms and signs of raise intra cranial pressure, normal brain neuroimaging, and high opening pressure ≥ 280 cm H2O in the presence of normal cerebro spinal fluid constituents. CASE PRESENTATION: Ten years old thin boy presented with severe throbbing headache, vomiting, and visual obscurations for a duration of 10 days. Physical examination revealed body mass index of 14.8, VI and VII cranial nerve palsies. Fudoscopy showed grade 4 papilledema; brain CT and MRI were normal. Lumbar puncture revealed pressure of 300 cm H2O with normal CSF constituents. He was treated with acetazolamide, methylprednisolone, and paracetamol. CONCLUSION: Pediatricians need to be more aware of idiopathic intracranial hypertension as it can lead to permanent vision loss.
