Abstract

Thyroglossal duct cyst is a common congenital cyst in the neck. The incidence of primary carcinoma of the thyroglossal duct is less than 1% in all age groups. We present the case of a 63-year-old man with rapid expansion of a known thyroglossal duct cyst with mixed solid/cystic components. F-FDG PET/CT showed a large anterior neck mass with a non-FDG-avid cystic component and a hypermetabolic heterogeneous mass on the right side confirmed by histopathology to be squamous cell carcinoma. Although rare, F-FDG PET/CT can assist with evaluating the extent of malignant involvement in thyroglossal duct cyst squamous cell carcinoma.

摘要

甲状舌管囊肿是颈部常见的先天性囊肿。在所有年龄段，甲状舌管原发性癌的发病率均低于 1%。我们报告了 1 例 63 岁男性，其已知甲状舌管囊肿迅速增大，伴有混合实性/囊性成分。F-FDG PET/CT 显示前颈部有一个大肿块，囊性成分无 FDG 摄取，右侧为代谢不均匀的肿块，组织病理学证实为鳞状细胞癌。虽然罕见，但 F-FDG PET/CT 可辅助评估甲状舌管囊肿鳞状细胞癌恶性累及的程度。
