The histopathological examination of the specimen revealed it to be ERMS T1NxM0 (Figure 1).
Whole abdomen CT images show abdominal mass prior to treatment (A), after 2 cycles of treatment (B), after 4 cycles of treatment (C), and after the whole treatment (8 cycles) (D).

During this hospitalization, we discovered that the abdomen and pelvis had neoplasms, with a diameter of ~31.6x10 cm by CT (Figure 2A). After the second and fourth cycles, the CT review showed that the abdominal and pelvis neoplasms were significantly reduced (Figure 2B and C). After the eighth cycle, CT indicated that the image was slightly better than the previous CT image (Figure 2D), and the PET/CT showed increased foci of brown adipose tissue that distributed weaker radioactivity all over the body compared with previous scans.
PET/CT images show abdomen area after the whole treatment (8 cycles).
