Bilateral inferior petrosal sinus sampling in the diagnosis of ACTH-dependent Cushing’s syndrome: experience in a tertiary hospital

Abstract

Bilateral inferior petrosal sinus sampling (BIPSS) is a useful test for differential diagnosis of central vs. ectopic adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (CS). We provide a description of the protocol used in our Center and an analysis of its diagnostic accuracy.
