Abstrakt:	Pseudotumor cerebri syndrome (PTCS), also known as idiopathic intracranial hypertension (IIH), is defined by elevated intracranial pressure in the absence of a structural or cerebrospinal fluid (CSF) abnormality. Typical features include headache, visual symptoms, and pulsatile tinnitus. Cranial nerve deficits are seen in a minority of cases, most often sixth nerve palsies. We present a unique cause of PTCS complicated by diffuse ophthalmoparesis and polyradiculopathy. A 27-year-old healthy woman presented with 2 weeks of blurry vision, diplopia, and facial and arm weakness. On examination, she had decreased visual acuity, markedly constricted visual fields in both eyes, with severe bilateral optic disc edema on fundus examination. There was diffuse ophthalmoparesis, right upper and lower facial weakness, and bilateral arm weakness. Magnetic resonance imaging brain revealed optic disc protrusion and a partially empty sella but no other abnormalities. Electromyogram (EMG) was consistent with bilateral C5-6 radiculopathies. Lumbar puncture revealed an opening pressure of 56 cm H2O with otherwise normal CSF constituents. She was treated with high-dose acetazolamide and methylprednisolone followed by optic nerve sheath fenestration. Due to progressive vision loss, she ultimately required ventriculoperitoneal shunting, after which her papilledema, ophthalmoparesis, and facial and arm weakness rapidly improved. This is a unique case of PTCS associated with diffuse ophthalmoparesis and polyradiculopathy. This constellation of abnormalities usually suggests an underlying inflammatory process in the subarachnoid space. However, once this has been excluded, the possibility of PTCS should be considered as early treatment can result in rapid reversal of symptoms and preserve visual function.
