The neuroendocrine tumor pheochromocytoma is usually detected via measurement of levels of catecholamines and their metabolites in plasma and urine. In patients with Parkinson disease, however, the results of these tests can be confounded by dopaminergic medications. Mehtaet al. present the case of a 59-year-old man with Parkinson disease in whom a diagnosis of pheochromocytoma was confirmed by means of structural and functional imaging.
