Adrenocortical Tumors: Recent Advances in Basic Concepts and Clinical Management

Figure 4. For the diagnosis of primary hypercortisolism, this algorithm suggests tests that are used for screening, confirmation, and localization of a cortisol-producing or corticotropin ( )-producing tumor. To convert serum cortisol values to nmol/L and to convert urine free cortisol values to nmol/d, multiply by 2.759. If there is more than one item, follow the respective numbers throughout the algorithm. BIPSS = bilateral inferior petrosal sinus sampling (measurement of plasma corticotropin concentrations in the inferior petrosal sinuses and a peripheral vein ); CRH = corticotropin-releasing hormone; CT = computed tomography; MRI = magnetic resonance imaging.
