Figure 1
Radiological images and histological findings of the primary tumor. Axial (A) T1-weighted and (B) T2-weighted MRI showed a heterogeneous, ill-defined mass measuring 53 × 48 × 120 mm in the right thigh. (C) Maximum intensity projection PET imaging demonstrated slight, heterogeneous 18 F-fluorodeoxyglucose uptake in the tumor (SUV = 3.5) (red arrow). Accumulation suggestive of metastasis was not found on PET/CT. (D) Microscopic examination of the resected specimen revealed the typical appearance of a myxoid liposarcoma with a large number of mature lipoblasts. No round-cell components were found.
