Papillary thyroid carcinoma in childhood frequently presents with locoregional lymph node metastases. The distant metastases often involve lungs and the bone, whereas brain metastasis is rare. We report a case of classic variant-papillary thyroid carcinoma with right cerebellar metastasis in a 7-year-old girl on a 123 I SPECT/CT study. A brain MRI on the same day shows a tiny millimetric enhancing nodule in the right cerebellum with no perceivable perilesional edema, confirming the 123 I scan findings.
儿童甲状腺乳头状癌常伴有局部淋巴结转移。远处转移常累及肺和骨骼，而脑转移少见。我们报告一例经典型变异型甲状腺乳头状癌，7 岁女孩行 123I SPECT/CT 检查示右小脑转移。同日行颅脑 MRI 检查示右小脑可见微小毫米强化结节，周围无明显水肿，与 123I 扫描结果一致。
