Pheochromocytomas develop spontaneously in 59% of 700-900 day-old males and in 81% of males 900 days or older. Almost always arise in the adrenal medulla, and about 50% occur bilaterally (Manger et al 1985). NEDH carrying transplanted pheochromocytomas have plasma norepinephrine concentrations 40-fold higher than age-matched controls, and provide a model of cardiomyopathy and other effects of prolonged exposure to catecholamines (Prokocimer et al 1987, 1988, Rosenbaum et al 1986, 1987, 1988).
