A 3-year-old boy with history of neuroblastoma underwent I-MIBG scan. The whole-body images showed relatively normal tracer distribution except for mild activity in the right foot, which was located in the first metatarsal on SPECT/CT images. The subsequent MRI scan of the right foot showed infiltration of the metatarsal of the right first toe. The findings were consistent with solitary acrometastasis of neuroblastoma to the great toe.
一位 3 岁男孩，曾患有神经母细胞瘤，进行了 I-MIBG 扫描。全身图像显示示踪剂分布相对正常，除了右脚有轻微活性，右脚第一跖骨在 SPECT/CT 图像上显示。随后对右脚进行的 MRI 扫描显示，右脚第一脚趾的跖骨有浸润。这些发现与神经母细胞瘤的单一肢端转移至大脚趾一致。
