False-Positive Uptake of 131I Due to Tubal Ligation in a Patient With Papillary Thyroid Cancer

ABSTRACTA 39-year-old woman with papillary thyroid cancer underwent I therapy after thyroidectomy. Posttherapeutic I 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 accumul...

Zusammenfassung:	ABSTRACTA 39-year-old woman with papillary thyroid cancer underwent I therapy after thyroidectomy. Posttherapeutic I 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 accumulation in the nearby uterus. Further inquiry discovered that she underwent tubal ligation 19 years ago. Our case demonstrates that I accumulation can occur at the site of oviducts many years after tubal ligation, which should be distinguished from I-avid metastases.
