Metastatic lesions of epithelioid sarcoma. FDG-PET identifies lesions with an increased uptake in the right neck (SUVmax; 4.6), right upper arm (SUVmax; 4.1 g/ml), left upper arm (SUVmax; 4.2 g/ml), right thigh (SUVmax; 5.5 g/ml) left thigh (SUVmax; 2.0 g/ml), back (SUVmax; 3.6 g/ml), and lower back (SUVmax; 4.6 g/ml), as well as the left axilla (SUVmax; 3.9 g/ml) (arrows) (A). CT with contrast medium shows a swollen axillary lymph node (B). Sagittal MRI section of the right thigh shows a nodular lesion associated with prominent longitudinal abnormal signal intensity on T2-weighted image (C). The nodular lesion shows iso-intensity on T1-weighted fat-suppression image (top), and heterogeneous high-intensity on T2-weighted image (middle) (D). Enhancement with gadolinium can be seen on T1-weighted fat-suppression image (bottom) (D).
