Although they may occur anywhere along the sympathetic chain, the vast majority arise from the adrenal gland. Where MRI is available it is the investigation of choice for staging since it does not involve ionising radiation. Distinguishing between the two is important, and a number of features are helpful. NBL arises from primordial neural crest cells that form the sympathetic nervous system, occurring anywhere along the sympathetic nervous system chain [1,2]. The tumours typically occur in infants and very young children (mean age of presentation being ~22 months) with 95% of cases diagnosed before the age of 10 years. Although most cases are sporadic and only 2% of cases are familial, a number of associations are recognised 1,2: The tumour typically arises from mesodermal precursors of the renal parenchyma (metanephros).
