Objective: The aim of this study was to evaluate the diagnostic accuracy of bilateral inferior petrosal sinus sampling (BIPSS) with desmopressin for pediatric Cushing’s disease (CD). Methods: We reviewed studies performed in children that evaluated the accuracy of BIPSS with desmopressin. Results: All included studies were case series of children with adrenocorticotropin hormone (ACTH)-dependent Cushing’s syndrome. The overall accuracy of BIPSS before stimulation was 84.1% (37/44), and after stimulation it was 92.3% (36/39). The overall lateralizing accuracy of BIPSS was 50.0%. Conclusion: Considering that available evidence is limited, it appears that BIPSS with desmopressin stimulation is accurate for the diagnosis of pediatric CD, but its lateralizing accuracy is probably not suitable for pediatric clinical practice.
