Bilateral inferior petrosal sinus sampling
Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the settin...
متن کاملThe role of bilateral inferior petrosal sinus sampling in the diagnostic evaluation of Cushing syndrome.
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 a...
متن کاملAssessment of bilateral inferior petrosal sinus sampling (BIPSS) in the diagnosis of Cushing's disease.
BACKGROUND The differential diagnosis of adrenocorticotropin (ACTH)-dependent Cushing's syndrome (CS) remains a challenging issue for clinical endocrinologists. In this respect, bilateral inferior petrosal sinus sampling (BIPSS) appears to be the most sensitive and specific test. Here, we report our 15-year experience of analyzing the performance of BIPSS, both in the correct diagnosis and in t...
متن کاملThe role of bilateral inferior petrosal sinus sampling in the diagnosis of Cushing's syndrome.
Adrenocorticotropin hormone (ACTH)-dependent Cushing's syndrome is most often due to a pituitary corticotroph adenoma, with ectopic ACTH-secreting tumors representing approximately 15% of cases. Biochemical and radiological techniques have been established to help distinguish between these two entities, and thus aid in the localization of the neoplastic lesion for surgical resection. The test t...
