Meta-iodobenzylguanidine (MIBG) is an analog of norepinephrine and guanethidine, and MIBG scintigraphy is useful to diagnose tumors of the sympathetic nervous system, such as pheochromocytoma, paraganglioma, and neuroblastoma. To date, there have been few reports of MIBG accumulation in gastrointestinal stromal tumors (GISTs), so the mechanism and frequency of MIBG accumulation in GISTs are unknown. Herein, we report and discuss three cases of GIST in which scintigraphy that was performed to exclude pheochromocytoma showed MIBG accumulation.
