Abstract

Peroperative localization of pheochromocytoma is the very crucial step for the successful removal of tumors. Computed tomography(CT) and magnetic resonance(MR) imaging have been commonly used for tumor localization, but in some cases of pheochromocytoma, such as extraadrenal location or distant metastasis of malignant tumor, their localization is somewhat difficult. Recently ^131 I-metaiodobenzylguanidine(MIBG) scintigraphy has been developed and increasingly used for the localization of pheochromocytoma and reported to be more sensitive and specific than CT or MR imaging in the cases of extraadrenal tumor location.We report a case of multiple extraadrenal pheochromocytoma in which ^131 I-MIBG scintigraphy clearly localized two intraabdominal and one bladder tumors, after failure of localization with conventional CT and MR imaging.

Key Words: Pheochromocytoma, Tumor localization
