Renal metastases from follicular thyroid cancer on SPECT/CT

Clin Nucl Med. 2007 Sep;32(9):751-2. doi: 10.1097/RLU.0b013e318125032e.


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.
