Role of Pre-operative Meta-Iodo Benzyl Guanidine (MIBG) in Biochemically Proven and Anatomically Localized Adrenal Pheochromocytoma

Abstract

Radio labeled metaiodobenzylguanidine scintigraphy (MIBG) is used for used to image pheochromocytomas. While computed tomography (CECT) or magnetic resonance imaging (MRI) usually localizes the tumor, MIBG is often obtained to rule out multifocal and metastatic disease and to corroborate anatomic imaging with functional data. Since the utility of routine MIBG is questionable in the pre-operative setting, the aim of this retrospective analysis was to look at this issue.
