Abstract
|
|
|
|
We report the case of a 32 year-old male with Chondroblastic Osteosarcoma of the skull, which was imaged with both 18[F]fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) and 68Gallium-arginine-glycine-aspartic acid (68Ga-RGD) PET/CT. The 18F-FDG PET/CT did not demonstrate the tumour, whereas the 68Ga-RGD PET/CT clearly depicted a left-sided frontal tumour. 68Ga-RGD PET/CT may be a clinically useful imaging modality for early detection of recurrent osteosarcoma, considering the limitations of 18F-FDG PET in a setting of low glycolytic activity.
