Karahalios et al. [3] postulated that cerebral venous hypertension causes impaired reabsorption of CSF across the arachnoid villi, leading to elevated CSF pressure. We report the case of a woman with pseudotumor cerebri in whom the pathogenesis and correct management could only be formulated after cerebral venography and manometry.
