Although increased MIBG activity in the colon is a well-described and well-known normal variant, elevated MIBG activity in the stomach is rarely seen. We describe increased 123I-MIBG accumulation in the stomach in a 13-year-old girl who had recurrent metastatic neuroblastoma. The activity appeared to be a new MIBG-avid lesion on the planar images. However, the SPECT/CT images revealed that the activity was inside the gastric lumen without anatomical abnormality. On a follow-up 123I-MIBG scan acquired 3 months later, the stomach no longer had elevated MIBG activity, while the other abnormal activity on prior study remained the same.
