Approach to the paediatric patient with suspected pheochromocytoma or paraganglioma versus neuroblastoma.

Abstract

Catecholamine producing tumours of childhood include neuroblastic tumours, phaeochromocytoma and paraganglioma (PPGL). PPGL and neuroblastic tumours can arise in similar anatomical locations and clinical presentations can overlap resulting in diagnostic challenges. Distinguishing between these tumour types is critical as management and long-term surveillance strategies differ depending on the diagnosis. Herein we describe two clinical cases and illustrate key considerations in the diagnostic work up of a neuroblastoma versus PPGL for patients presenting with adrenal, pelvic, and retroperitoneal masses in childhood.
