Cardiac pheochromocytomas detected by Tc-99m-hydrazinonicotinyl-Tyr3-octreotide (HYNIC-TOC) scintigraphy.
Primary pheochromocytomas of the heart are extremely rare tumors and difficult to diagnose. Iodine labeled metaiodobenzylguanidine (MIBG) is the first choice of the nuclear medicine modality in the evaluation of adrenal pheochromocytoma. However, the sensitivity of MIBG in the diagnosis of extraadrenal pheochromocytoma is less optimal. In this preliminary report, the efficacy of octreotide scintigraphy using Tc-99m labeled hydrazinonicotinyl-Tyr3-octreotide (HYNIC-TOC) in the evaluation of primary cardiac pheochromocytoma was assessed.
