Asymmetric thoracic metaiodobenzylguanidine (MIBG) activity due to prior radiation therapy.
A 5-year-old patient suffered Horner syndrome, which was caused by a neuroblastoma in the left apex of the lung shown on the initial I-MIBG scan. After the surgical resection and external radiation to the left lung field, a follow-up I-MIBG scan revealed significantly less MIBG activity in the left upper chest compared to the contralateral right upper chest.
