Catecholamines in neuroblastoma: Driver of hypertension, or solely a marker of disease?

Although multifactorial, hypertension in neuroblastoma often has a neuroendocrine component. Excess normetanephrine production in neuroblastoma may be a more common hypertensive mechanism than previously appreciated. Urinary normetanephrine elevation could suggest potential neuroendocrine-mediated hypertension.
