Pseudotumor cerebri, empty sella syndrome, and adrenal adenoma

Benign intracranial hypertension (BIH) and empty sella syndrome occurred in a patient with Cushing syndrome resulting from adrenal adenoma, removal of which was followed by return of cerebrospinal fluid pressure to normal. This case does not clarify the pathophysiology of BIH, but it does raise questions about the treatment of BIH with corticosteroids, which are of unproved efficacy and may sometimes cause the same clinical syndrome.
