A case of dedifferentiated liposarcoma showing a biphasic pattern on 2-deoxy-2-f(18)-fluoro-d-glucose positron emission tomography/computed tomography.

[well-differentiated liposarcoma]

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 .
