Ganglioneuromas are usually considered not to be functionally active. Studies of their catecholamine excretory pattern and of their imaging by means of the adrenergic tracing agent 131-I-MIBG have been therefore sparse. We report on a case of secretory ganglioneuroma, as demonstrated by the increased urinary excretion of the catecholamine metabolites HVA and VMA, increased plasma dopamine and epinephrine levels, and positive 131-I-MIBG scintigraphy. We must therefore be aware that a functionally active tumor is not necessarily a neuroblastoma, and that the diagnosis should be biopsy proven.
