title: The role of bilateral inferior petrosal sinus sampling in the diagnostic evaluation of Cushing syndrome.
abstract: Bilateral inferior petrosal sinus sampling is the gold standard diagnostic assay     in identifying the pituitary source of adrenocorticotropic hormone secretion in     Cushing syndrome. The noninvasive assays used in the workup of Cushing syndrome     are often misleading or ambiguous, yielding sensitivities of up to only 80%.     Inferior petrosal sinus sampling, however, is highly accurate and safe when     performed in experienced centers. We review here the historical and technical     details of the procedure, with emphasis on the relevant anatomy and a discussion     of possible rare complications.
