Uterine myoma may serve as a false positive source of radioiodine uptake in whole body scintigraphy

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 ۴۶-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.
