Papillary thyroid cancer (PTC) is the most common type of thyroid malignancy and is characterized by slow growth and an indolent biological behavior. Papillary thyroid microcarcinoma is the PTC with the maximum size of the tumor <1cm, considered the most indolent form of thyroid cancer. PTC is usually metastasizes in cervical lymph nodes, lungs and bones and, less commonly, in brain or liver. Skeletal muscle metastases from PTC are extremely rare, a retrospective review of the literature revealed only 13 case reports. Among them, six cases are solitary skeletal muscle metastases, and seven are multiple metastases, most of them being associated with lung lesions. It seems that PTC is prone to metastasizing to the erector spinae and thigh muscles groups with unique cases located in trapezoid, biceps, deltoid, gastrocnemius and rectus abdominis muscles. Although extremely rare, one must bear in mind the fact that muscle metastasis from PTC is possible, and that is the reason we would like to discuss the existing clinical cases and to add a unique case of solitary skeletal muscle metastasis from papillary microcarcinoma.

Abstract Context: PET CT imaging methods based on fibroblast activation protein inhibitors (FAPIs) have recently demonstrated promising clinical results. Objective: We aimed to evaluate the use of 68Ga-FAPI PET / CT and 18FDG PET / CT imaging techniques to detect the metastatic foci in recurrent papillary thyroid carcinoma.Design and Patients: This is a prospective study. Patients who were diagnosed with papillary thyroid carcinoma, achieved biochemical recovery after the first operation and having recurrence for papillary thyroid carcinoma on the follow up were included in the study. [68Ga] Ga-DOTA-FAPI-04 and [18F] FDG PET / CT were performed for comparative purpose and detection of recurrence localization.Results: [18F] FDG PET / CT detected the metastatic foci in 21 of 29 patients (72.4%), [68Ga] Ga-DOTA-FAPI-04 was able to detect the metastatic foci in 25 of 29 patients (86.2%). When the two imaging techniques were used together, the metastatic foci in 27 of the 29 patients could be detected (93.1%.). Also between the [18F] FDG PET / CT SUVmax values and [68Ga] Ga-DOTA-FAPI-04 SUVmax values, a statistical significance was found in favor of 68Ga-FAPI PET (p = 0,002).Conclusion: In conclusion, 68Ga-FAPI PET imaging technique can be used as an alternative method to detect the metastatic focus or foci in patients with recurrent papillary thyroid carcinoma. It can also increase the chance of metastatic focus or foci detection when used in conjunction with the 18 FDG PET.
