Dear Sir, Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a disorder of elevated intracranial pressure in the absence of localizing neurological signs, intracranial mass lesions or cerebrospinal outflow obstruction (1). The usual presentation is headache, pulsatile tinnitus, papilledema, visual disturbances, diplopia and vomiting (2,3). However, in some cases, involvement of cranial nerves can accompany and make the diagnosis difficult. We report a female case presented with headache, nausea, vomiting, diplopia, unilateral abducens nerve palsy with papilledema and diagnosed with IIH.
