The metastasis of papillary thyroid carcinoma to the parapharyngeal space is rare and discussed in the English literature before. Encountering a parapharyngeal mass with cystic appearance on imaging, one should rule out thyroid malignancy as differential diagnosis.
The case presented here is a 22-year-old woman who was referred to our clinic with complaints of painless neck mass, dysphagia and hoarseness for two years. After radiologic and pathological examination, the mass thought to be relevant with the thyroid gland. Peroperatively, the tumor was found to originate from the superior pole of the right thyroid gland, with a narrow stalk, and extended following the neurovascular bundle to the lower part of the parapharyngeal space. The bulk was removed via transservical approach with total thyroidectomy.
The occurrence of the follicular variant of papillary thyroid carcinoma in the parapharyngeal space is extremely rare. The management of this rare case was discussed with the review of literature.
甲状腺乳头状癌转移至咽旁间隙极为罕见，此前英文文献中有相关讨论。影像学检查发现咽旁有囊性肿物时，鉴别诊断应排除甲状腺恶性肿瘤。
本文病例为一名22岁女性，因无痛性颈部肿物、吞咽困难及声音嘶哑两年前来我院就诊。经放射学及病理学检查，该肿物被认为与甲状腺有关。手术中发现肿瘤起源于右甲状腺上极，有一狭窄蒂部，沿神经血管束延伸至咽旁间隙下部。通过经颈入路行甲状腺全切除术切除肿物。
甲状腺乳头状癌滤泡变异型在咽旁间隙极为罕见。结合文献复习对该罕见病例的处理进行了讨论。
