Right Ventricle Metastasis of Pleomorfic Undifferentiated Sarcoma Detected by FDG PET/CT and Three‐Dimensional Echocardiography

Image: A 70-year-old man had a history of high-grade undifferentiated pleomorphic sarcoma of the left proximal femoral region that was treated with surgical excision (including amputation) and postoperative chemotherapy. At 1 year of the treatment, FDG PET/CT whole-body image showed isolated intense focal FDG uptake of soft tissue lesion at the lateral side of left gluteal region that suggested metastasis of primary tumor (Fig. 1). There was no pathological FDG
