title: A case of dedifferentiated liposarcoma showing a biphasic pattern on 2-deoxy-2-f(18)-fluoro-d-glucose positron emission tomography/computed tomography.
abstract: Integrated 2-deoxy-2-F(18)-fluoro-D-glucose positron emission tomography combined with computed tomography (FDG-PET/CT) has been used in the field of soft tissue sarcoma. We report an 81-year-old man with dedifferentiated liposarcoma in the left thigh, which was composed of well-differentiated liposarcoma and pleomorphic malignant fibrous histiocytoma. As well as other radiological modalities, FDG-PET was able to demonstrate a biphasic signal pattern composed of well-differentiated liposarcoma and dedifferentiated area, being consistent with the histological grade of malignancy.
