Abstract

Chest CT images were acquired in a 79-year-old man to evaluate a right lung mass revealed by chest radiography. The image findings suggested possible pulmonary malignancy. FDG PET/CT was performed for staging, which displayed not only a hypermetabolic mass in the upper lobe of right lung but also increased FDG uptake of the spinal cord at T11 to T12 level. A lesion corresponding to the hypermetabolic region of the spinal cord was revealed by MRI. The intramedullary spinal cord metastasis from lung squamous cell carcinoma was confirmed through the pathological examination after the spinal cord lesion was resected.

摘要

胸部 CT 图像是为了评估胸部 X 线检查发现的右肺肿块而采集的，该 79 岁男性患者。图像结果提示可能为肺部恶性肿瘤。为了进行分期，进行了 FDG PET/CT 检查，结果不仅显示右上肺代谢活跃的肿块，还显示 T11 至 T12 水平脊髓 FDG 摄取增加。MRI 显示与脊髓高代谢区域相对应的病变。在切除脊髓病变后，通过病理检查证实了来自肺鳞状细胞癌的脊髓内转移。
