FDG PET–CT in detection of diaphragmatic metastasis of dedifferentiated liposarcoma: A case report

Dedifferentiated liposarcoma is an aggressive soft tissue disease, with a prognosis critically depending on a timely detection of the primary and metastatic lesions. We present here a rare case of diaphragmatic metastasis from a recurrent liposarcoma of the colon, demonstrating the important contribution of FDG PET and CT imaging to disease management: FDG PET/CT imaging allowed the identification of this unusual metastatic site and a complete clinical remission by the surgical excision of the lesion. These data support the systematic inclusion of FDG PET/CT scans in the follow-up of high-grade soft tissue tumors.
