Abstract

A 69-year-old man presented with bulging of the right oropharyngeal wall, which revealed cytopathologically malignant cells. The man underwent MRI and F-FDG PET/CT, which demonstrated a cystic parapharyngeal lesion with an F-FDG-avid soft tissue component and right cervical lymph node. The patient was operated on and showed thyroid cancer in normal thyroid tissue, compatible with a papillary thyroid carcinoma in a lateral thyroglossal duct cyst and 2 ipsilateral lymph node metastases. Despite its rarity, papillary thyroid carcinoma in a thyroglossal duct cyst should be kept as one of the differential diagnoses in patients presenting with parapharyngeal cystic lesion.

摘要

一位 69 岁男性因右侧口咽壁膨出就诊，细胞学检查显示恶性细胞。该男性接受了 MRI 和 F-FDG PET/CT 检查，结果显示咽旁间隙囊性病变伴 F-FDG 摄取的软组织成分和右侧颈部淋巴结。患者接受了手术，在正常甲状腺组织中发现甲状腺癌，符合甲状腺舌管囊肿旁的甲状腺乳头状癌，且伴有 2 个同侧淋巴结转移。尽管罕见，但对于表现为咽旁间隙囊性病变的患者，甲状腺舌管囊肿内的甲状腺乳头状癌也应作为鉴别诊断之一。
