MIBG Uptake in Pancreas as a Normal Variant

A 5-year-old girl with high-risk neuroblastoma underwent 123I-MIBG scintigraphy for disease restaging. The whole-body images showed a faint MIBG uptake in the midabdomen. Abdominal SPECT/CT demonstrated the focus locating in the pancreatic head. However, this activity disappeared on delayed acquisition at 6-hour later. Follow-up MIBG scan after 6 months did not show the abnormal MIBG uptake in the pancreatic head. Delayed scan could be helpful for differential diagnosis.
