title: Sipple's syndrome with liver tumors examined by iodine-131 MIBG and technetium-99m(V)-DMSA.
abstract: This case report describes the localization and categorization of tumors using 99mTc(V)-dimercaptosuccinic acid and [131I]metaiodobenzylguanidine scans in a very uncommon case of medullary thyroid carcinoma associated with pheochromocytoma (Sipple's syndrome) and hepatocellular carcinoma. Technetium-99m(V)-dimercaptosuccinic acid showed accumulation only in medullary thyroid carcinoma, but [131I]metaiodobenzylguanidine scans were positive in both medullary thyroid carcinoma and pheochromocytoma. In advanced Sipple's syndrome, combined use of [99mTc(V)]dimercaptosuccinic acid and [131I]metaiodobenzylguanidine may be useful for the categorization of tumor mass lesions and planning appropriate therapy.
