Pseudotumor cerebri, or idiopathic intracranial hypertension (IIH), is a 
syndrome of elevated intracranial pressure (ICP) of unknown etiology that occurs 
predominantly in obese women of childbearing age. Pseudotumor cerebri literally 
means "false brain tumor". It is a "diagnosis of exclusion" therefore a complete 
work-up to rule out life-threatening causes for increased ICP must be performed 
through a comprehensive history, complete physical examination, diagnostic 
imaging, and cerebrospinal fluid (CSF) analysis before the diagnosis can be 
made. The authors present the case of a young woman with headache, and near 
blindness due to pseudotumor cerebri. The presentation, diagnosis, and treatment 
options are discussed.
