Idiopathic intracranial hypertension is charactericed by increased intracranial pressure in the absense of a space occupying lesion or obstruction to the circulation of cerebroespinal fluid (CSF). Usually self-limited, but often relapsing. Diagnosis is based on a record of intracranial pressure of over a limit of 250 mmH2O. Bilateral papilloedema and paresia of the VI cranial nerve is seen in most patients. Morbidity is basically due to possible loss of vision associated with atrophy of the optic nerve. Management include administration of acetazolamide, repeated lumbar punctures and weight loss. Magnetic resonance (MR) imaging demostrated «empty sella», subarachnoid spaces are enlarged, distension of the perioptic subarachnoid space and enhancement of the prelaminar optic nerve
