摘要：

A 39-year-old woman with papillary thyroid cancer underwent I-131 therapy after thyroidectomy. Posttherapeutic I-131 whole-body scan accidentally showed symmetric hot spots in the pelvic region beyond known bone metastases. SPECT/CT was immediately added and revealed metal artifacts with I-131 accumulation in the nearby uterus. Further inquiry discovered that she underwent tubal ligation 19 years ago. Our case demonstrates that I-131 accumulation can occur at the site of oviducts many years after tubal ligation, which should be distinguished from I-131-avid metastases.
