Persistence of primary empty sella syndrome despite obesity surgery: report of two unusual cases

Primary empty sella syndrome (ESS) shares with idiopathic intracranial hypertension (IIH) high intracranial pressure (ICP) and association with obesity. Bariatric surgery is effective in IIH treatment; no data, however, exist about ESS. We report two overweight ESS patients in whom bariatric surgery resolved obesity but failed in curing ESS, requiring cerebrospinal fluid (CSF) shunt placement.
