    Iodine/FDG ""Flip-Flop"" Phenomenon Inside a Large Metastatic Thyroid Cancer Lesion Better Characterized on SPECT/CT and PET/CT Studies
    (2018) DUARTE, Paulo Schiavom; MARIN, Jose Flavio Gomes; CARVALHO, Jose Willegaignon de Amorim de; SAPIENZA, Marcelo Tatit; BUCHPIGUEL, Carlos Alberto
    Iodine/FDG flip-flop phenomenon inside large metastatic thyroid cancer lesions has been rarely described. We present a case of this phenomenon better characterized using SPECT/CT and PET/CT studies.

    Brain Metastasis of Medullary Thyroid Carcinoma Without Macroscopic Calcification Detected First on 68Ga-Dotatate and Then on 18F-Fluoride PET/CT
    (2018) DUARTE, Paulo Schiavom; MARIN, Jose Flavio Gomes; CARVALHO, Jose Willegaignon De Amorim De; SAPIENZA, Marcelo Tatit; BUCHPIGUEL, Carlos Alberto
    We report a case of a medullary thyroid carcinoma noncalcified brain metastasis characterized on Ga-68-dotatate PET/CT but not on an F-18-fluoride PET/CT performed 1 month later. Subsequent F-18-fluoride PET/CT studies performed 7 and 19 months after the Ga-68-dotatate PET/CT study demonstrated focal uptake in the metastasis. The CT images of the last PET/CT study also depicted a small focus of calcification beginning in the metastatic site.

    Visualization of Lymph Nodal and Hepatic Metastases of Medullary Thyroid Carcinoma on F-18-Fluoride PET/CT
    (2015) VALE, Romulo Hermeto Bueno do; MARIN, Jose Flavio Gomes; DUARTE, Paulo Schiavom; SAPIENZA, Marcelo Tatit; BUCHPIGUEL, Carlos Alberto
    F-18-fluoride uptake in soft tissue metastases has been previously described. Herein, we report a case of F-18-fluoride uptake in lymph nodal and hepatic metastases of medullary thyroid carcinoma. Simultaneous CT showed calcified lesions in these regions.

    18F-Fluoride Uptake in Soft Tissue Metastases of Medullary Thyroid Carcinoma as a Marker of Progressive Calcification
    (2018) DUARTE, Paulo Schiavom; MARIN, Jose Flavio Gomes; COURA FILHO, George Barberio; SAPIENZA, Marcelo Tatit; BUCHPIGUEL, Carlos Alberto
    F-18-fluoride (F-18-NaF) uptake in soft tissue metastases of medullary thyroid carcinoma (MTC) has been reported. However, the evolution of these metastatic sites has rarely been assessed. We present a case of F-18-NaF uptake in multiple liver metastases of MTC initially without macroscopic calcification. The CT follow-up studies showed a progressive calcium deposition in the lesions. Therefore, this case suggests that the F-18-NaF uptake in MTC metastases could potentially be a marker of an ongoing calcification process instead of an inert deposit of calcium.
