A 74-year-old woman underwent I-131 MIBG imaging to rule out or confirm a left adrenal pheochromocytoma. Significant uptake was seen in the left side of the abdomen. Postcontrast coronal MRI revealed that this agent did not accumulate in the mass but rather in the kidney. The left kidney was compressed by the mass and developed hydronephrosis. Accumulation of I-131 MIBG in the left kidney was considered to be due to urinary stasis.
