Renal metastases from follicular thyroid cancer on SPECT/CT.
In well-differentiated thyroid carcinoma, only a subset of patients develop distant metastases, predominantly to the lungs and the skeletal system. Only a few cases of metastatic spread to the kidneys are described in the literature. We report the case of a 64-year-old woman with a long history of follicular thyroid cancer who developed renal metastases. The lesions were detected with I-131 scintigraphy, SPECT/CT and thin-collimated contrast-enhanced CT. Subsequent surgery and histopathologic analysis of the renal lesions confirmed the diagnosis.
