Abstract:
: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.

杂志文章abstract::Dermatofibrosarcoma protuberans is a rare cutaneous tumor that is locally aggressive and has a high rate of recurrence after surgical excision. The tumor grows slowly, typically over years. On rare occasions, metastasis to distant sites (especially the lung) or regional lymph nodes may occur. Here, we present F-FDG PE...
