Understanding the occurrence of false positive results for radioactive iodine absorption in whole body scans is crucial for differentiating these cases from actual metastases. The implementation of SPECT/CT technology has significantly facilitated this process for medical professionals. This study presents a case involving a 46-year-old female patient who underwent a total thyroidectomy as a treatment for thyroid cancer (papillary thyroid carcinoma), followed by radioactive iodine therapy. The post-treatment whole body scan revealed the presence of a diffuse radioiodine-avid lesion in the pelvic region, which was later identified as multiple uterine myomas through additional investigations utilizing SPECT/low-dose CT scan and MRI findings.
