Abstract:
Second malignancy as a long-term complication in survivors of advanced-stage neuroblastoma is rare, but it is becoming recognized more frequently. We report an unusual case of a soft-tissue sarcoma developing within a retroperitoneal primary following previous extensive treatment for metastatic neuroblastoma using multimodality imaging including PET/CT.
