Usefulness of scintigraphic imaging using 131iodine-metaiodobenzylguanidine in localization of asymptomatic pheochromocytoma.
Localization of either multiple, metastatic and/or asymptomatic pheochromocytomas sometimes is elusive because all imaging methods to date have been nonspecific in character. We report 2 cases in which scintigraphy was used with a new radiopharmaceutical agent, 131iodine-metaiodobenzylguanidine, for the accurate localization of pheochromocytoma. To the best of our knowledge, this is the first report of asymptomatic pheochromocytoma imaged by 131iodine-metaiodobenzylguanidine scintigraphy.
