- 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 AlbertoIodine/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 AlbertoWe 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.
