Thyroid cancer rarely metastasizes to the parapharyngeal space. A inconsistent lymphatic drainage pathway is involved, as described by Rouvière.
To demonstrate the interest of [18 F]-FDG PET in early diagnosis of metastasis and in the follow up of the patient.
40 y.o. male with papillary carcinoma who had a secondary parapharyngeal metastasis. The diagnosis of recurrence was difficult, as the plasmatic thyglobulin was low, and the iodine scan was not informative. In this case, [18 F]-FDG PET-CT was informative (clear parapharyngeal fixation) and led to the diagnosis of recurrence.
It appears that 18F FDG PET has a good diagnostic value and that its sensitivity is better than CT scan and MRI. Some authors recommend the use of [18 F]-FDG PET and scintigraphy with Iodine 131 to screen patients with thyroid cancer recurrences.
甲状腺癌很少转移至咽旁间隙。如鲁维耶所描述，其涉及不一致的淋巴引流途径。
证明[18F]-FDG PET在转移灶早期诊断及患者随访中的价值。
一名40岁男性，患有乳头状癌并伴有咽旁继发性转移。由于血浆甲状腺球蛋白水平低且碘扫描无诊断价值，复发的诊断较为困难。在此病例中，[18F]-FDG PET-CT提供了有价值的信息（明确的咽旁固定），从而得以诊断复发。
看来18F FDG PET具有良好的诊断价值，其敏感性优于CT扫描和MRI。一些作者建议使用[18F]-FDG PET和碘131闪烁显像来筛查甲状腺癌复发患者。
