Figure 1 Basal contrast-enhanced abdominal CT scan. The large retroperitoneal mass is indicated by the white arrow.

Figure 2 Contrast-enhanced abdominal CT scan performed. The large retroperitoneal mass is reduced in size but a residual disease of about 1 cm is localized at celiac trunk (white arrow).

Figure 3 Total-body FDG-PET performed after the seventh course of treatment.

Figure 4 Contrast-enhanced CT performed 4 mo after the completion of the treatment. A minimal residual disease is localized at the celiac tripod.

Figure 5 FDG-PET performed in October 2003: a complete remission of the disease is showed.
