Abstract:
The positive predictive value of MIBG scintigraphy in the evaluation of neuroblastoma is very high, and false-positive findings are rare. We present here persistently elevated MIBG activity in the liver caused by external beam radiation, which could be misinterpreted as malignant involvement if history and prior studies were not carefully correlated.
