Intramedullary spinal cord metastases (SCMs) are extremely rare. Here, we report a case of a 60-year-old man with a history of right nonsmall cell lung cancer treated by concomitant radiochemotherapy who complained, 9 months after treatment completion, of chest pain, breath shortness, and more recently back pain. An F-FDG PET/CT was performed as part of the restaging process and showed a hypermetabolic mass of the right lung in addition to ipsilateral mediastinal hypermetabolic lymph nodes. There was also an FDG avid lesion of thoracic spinal cord at the T11-T12 level consistent with SCM as confirmed by MRI.

脊髓髓内转移瘤（SCMs）极为罕见。在此，我们报告一例60岁男性病例，该患者有右非小细胞肺癌病史，接受过同步放化疗，在治疗结束9个月后，出现胸痛、气短，近期还出现背痛。作为再分期检查的一部分，进行了F-FDG PET/CT检查，结果显示右肺有一个高代谢肿块，同侧纵隔也有高代谢淋巴结。此外，MRI证实，在T11-T12水平的胸段脊髓有一个FDG摄取增加的病灶，符合脊髓髓内转移瘤。
