Abstract

A 55-year-old woman with papillary thyroid carcinoma under total thyroidectomy and cervical lymph node dissection was referred for I radioiodine therapy. Posttherapeutic whole-body scintigraphy revealed increased focal uptake in the right upper abdomen, which localized to the region of the head of the pancreas on SPECT/CT fusion images. Further evaluation with MRI affirmed the radioiodine retention corresponded to bile duct dilation.

摘要

一位 55 岁女性，因甲状腺乳头状癌行甲状腺全切除术和颈部淋巴结清扫术，后转至我科行 I 放射性碘治疗。治疗后全身闪烁扫描显示右中上腹部放射性摄取增加，SPECT/CT 融合图像上定位于胰头部。进一步行 MRI 检查证实放射性碘滞留与胆管扩张相对应。
