Transient, unilateral, complete, oculomotor palsy in an adult patient with idiopathic intracranial hypertension

Idiopathic intracranial hypertension (IIH) is a well recognized condition of elevated intracranial pressure of unknown cause. Many etiologies have been proposed, but few- besides a high body mass index, hypervitaminosis A, steroid withdrawal, exposure to tetracyclines and female gender- have been proven. The main morbidity in this condition is visual loss and is often reversed if recognized early and treated promptly with weight- reduction, a low-sodium diet and acetazolamide.
