Transsphenoidal surgery for cushing disease after nondiagnostic inferior petrosal sinus sampling.
BACKGROUND Inferior petrosal sinus sampling (IPSS) is a useful technique for confirming a pituitary source of adrenocorticotropic hormone (ACTH) overproduction in Cushing disease. Uncertainty remains regarding the appropriate course of therapy when an ectopic tumor is predicted by IPSS but none can be found and in circumstances when the procedure cannot be successfully completed owing to techni...
متن کاملDiagnostic errors after inferior petrosal sinus sampling.
Although inferior petrosal sinus sampling (IPSS) is useful in the evaluation of Cushing's syndrome, false negative cases have been described, and many patients presumed to have ectopic tumors based upon negative IPSS remain without a final diagnosis. These patients are often managed as if they have as yet undiscovered ectopic tumors. To test this assumption, we conducted a retrospective review ...
متن کاملBilateral 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 کاملNeurologic complications of inferior petrosal sinus sampling.
BACKGROUND AND PURPOSE Inferior petrosal sinus sampling (IPSS) is a useful diagnostic technique in adrenocorticotropic hormone (ACTH)-dependent hypercortisolism with normal or equivocal MR imaging. The procedure is believed to be safe, with mostly minor complications. However, there are rare, but severe, neurologic complications that need to be considered. MATERIALS AND METHODS We performed a...
