Key result
18F-FDG PET/CT and 68Ga-DOTATATE PET/CT demonstrated similarly increased imaging agent uptake in a rare case of primary extraskeletal Ewing sarcoma of the neck.
Why the study?
Primary extraskeletal Ewing sarcoma in the soft tissue of the neck is rare.
Both 18F-FDG and 68Ga-DOTATATE PET/CT demonstrated increased uptake in a rare case of extraskeletal Ewing sarcoma of the neck.
Both FDG and DOTATATE PET show uptake in rare neck Ewing sarcoma; leaves open their diagnostic role pending further study.
Primary extraskeletal Ewing sarcoma in the soft tissue of the neck is rare. A 29-year-old woman underwent 18F-FDG PET/CT and 68Ga-DOTATATE PET/CT for a mass in her neck. The patient complained of pain in the right side of the neck for 6 months. Both scans showed increased imaging agent uptake in the neck mass, which was subsequently diagnosed as extraskeletal Ewing sarcoma.
