Abstract
Idiopathic intracranial hypertension (IIH) usually presents with headache, papilledema, and sixth nerve palsy, but atypical manifestations can delay diagnosis. Atypical presentations in the present case series were trigeminal neuralgia, focal seizures with Todd’s paresis, hypoglossal nerve palsy, intractable migraine like headache, orthostatic intolerance and spontaneous CSF rhinorrhea. Most patients improved with medical therapy, with only two requiring surgical intervention. These findings emphasize that atypical IIH is not uncommon and that measuring cerebrospinal fluid opening pressure is essential for timely diagnosis.
