title: Localization of adrenal and extra-adrenal pheochromocytomas by magnetic resonance imaging.
abstract: We found magnetic resonance imaging helpful in the localization of both an adrenal and an extra-adrenal pheochromocytoma, since these tumors produced a high-intensity "light bulb" image. MRI is an excellent method for localizing pheochromocytomas because it detects adrenal and extra-adrenal pheochromocytomas missed by computerized tomography and adrenal-renal ultrasonography, and because the high-intensity MRI signal generated by pheochromocytomas is useful in differentiating them from nonfunctioning adrenal masses in hypertensive patients.
