Malignant extrarenal rhabdoid tumor (ERRT) is a very rare type of soft-tissue sarcoma with a reported incidence of 0.3% of all soft-tissue sarcomas. Only 7 cases of spinal malignant ERRT have been reported in the literature, and to our knowledge, F-18 FDG PET/CT imaging for staging and evaluation of response to therapy for these tumors has not been previously described. This is a case of an 8-month-old boy with malignant ERRT of the spine, who was staged with F-18 FDG PET/CT, and had his tumor burden assessed with PET/CT after chemotherapy, which altered the subsequent chemotherapy regimen.
恶性肾外横纹肌样瘤 (ERRT) 是一种非常罕见的软组织肉瘤，其发病率占所有软组织肉瘤的 0.3%。文献中仅报道了 7 例脊柱恶性 ERRT，据我们所知，目前尚未有 F-18 FDG PET/CT 成像用于这些肿瘤的分期和治疗反应评估的报道。本病例为 8 月龄男性，患有脊柱恶性 ERRT，通过 F-18 FDG PET/CT 进行分期，并在化疗后用 PET/CT 评估肿瘤负荷，从而改变了后续的化疗方案。
