A 61-year-old woman with newly diagnosed anaplastic thyroid cancer and known metastases to the brain, lungs, and adrenal glands complained of groin muscle pain. F-FDG PET/CT was performed to assess for extent of disease and showed extensive hypermetabolic lesions throughout the skeletal musculature concerning for metastatic disease. As this would be a very rare presentation for anaplastic thyroid carcinoma, a biopsy of the left gluteal muscle was conducted. Pathology demonstrated anaplastic thyroid carcinoma, metastatic to skeletal muscle.
一位 61 岁女性，新诊断为间变性甲状腺癌，已知有脑、肺和肾上腺转移，诉腹股沟肌肉疼痛。进行 F-FDG PET/CT 检查以评估疾病范围，显示整个骨骼肌广泛代谢活跃，考虑转移疾病。由于这是间变性甲状腺癌非常罕见的表现，因此对左侧臀肌进行了活检。病理显示间变性甲状腺癌转移至骨骼肌。
