Scintigraphic localization of a recurrent phaeochromocytoma by means of iodine-131 metaiodobenzylguanidine.
A new adrenomedullary scintigraphic imaging agent, iodine-131-labelled metaiodobenzylguanidine (MIBG), was used to localize a recurrent phaeochromocytoma in a 27-year-old man in whom the site of tumour could not be determined by any other means. MIBG scintigraphy is easy to perform and is highly specific for functioning aberrant adrenomedullary tissue. It complements other methods for localization of phaeochromocytoma and, under some circumstances, it may become the initial imaging procedure of choice in the screening of patients in whom the biochemical or clinical evidence suggests the presence of such tumours.
