False-positive diagnosis of adrenal pheochromocytoma on iodine-123-MIBG scan

J Endocrinol Invest. 1998 Dec;21(11):779-83. doi: 10.1007/BF03348046.

Abstract

1-123 metaiodobenzylguanidine (1-123 MIBG) scintigraphy is known for its high specificity in detecting pheochromocytoma and other tumors of neural crest origin. In this rare case report, we describe a definite adrenocortical adenoma that demonstrated false-positive uptake at I-123 MIBG scintigraphy and a remarkable accumulation of 75-SE-6-beta-selenomethyl-norcholesterol.
