Spinal metastases are rare in head and neck cancer. We present a rare case of vocal cord squamous cell cancer that metastasized to the spinal cord and cauda equina. A 63-year-old man presented with acute back pain and bilateral leg weakness 5 months after having a surgical treatment for moderately differentiated vocal cord squamous cell cancer (T2 N0 M0). Restaging F-FDG PET examination demonstrated a soft tissue mass with intense hypermetabolism in the distal spinal cord and a hypermetabolic leptomeningeal metastatic deposit at the L3 level. The findings were confirmed on MRI prior to treatment.
脊柱转移在头颈部癌症中较为罕见。我们报告一例罕见的声带鳞状细胞癌病例,该肿瘤转移至脊髓和马尾。一名 63 岁男性在接受中分化声带鳞状细胞癌(T2N0M0)的手术治疗后 5 个月出现急性背痛和双侧下肢无力。重新分期 F-FDG PET 检查显示在远端脊髓中有软组织肿块,伴有强烈的高代谢,在 L3 水平有高代谢性脑膜转移灶。在治疗前 MRI 上证实了这些发现。
