Özet: Abstract A 45 years old man with the diagnosis of myxoid liposarcoma in posterior part of his right thigh underwent [18F]-2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) for staging purpose. In posterior of the middle and distal 1/3 parts of the right femur, a soft tissue mass measuring 105x92 mm with lobulated contours pushing neighboring muscles was detected which included septated myxoid-cystic and fat components on CT images and showed heterogeneously increased FDG uptake (SUVmax: 3.35) on FDG-PET/CT fusion images. No evidence of metastasis could be detected on other FDG PET/CT images and the tumor was removed totally after imaging. FDG PET/CT is being used for grading purpose in soft tissue sarcomas and plays important role in determining the site for biopsy. FDG PET/CT was found to be useful in staging of our case with myxoid liposarcoma because of its contribution to metastasis evaluation.
