We present a rare case of recurrent dedifferentiated liposarcoma of the spermatic cord which was clearly depicted by FDG-PET imaging Preceding the FDG study, it was difficult to discriminate whether a mass detected by CT was recurrent tumor or postradiation necrosis. The FDG-PET finding was informative in relation to the extent of a viable tumor. We suggest that FDG- PET seems to be useful in differentiating recurrent tumor from radiation necrosis in patients with liposarcoma after therapy.
