Plain radiograph of the pelvic bone showed osteolytic changes of the left iliac bone (Figure 1).
(a) 7.2 x 9.5 x 3.0 cm mass arising from the left iliac bone and extended into the sacral bone. (b) The large mass showing low intensity on T1-weighted images and high intensity on T2-weighted images and sparsely enhanced by contrast agent.

CT and MRI demonstrated that a 7.2 x 9.5 x 3.0 cm tumor arising from the left iliac bone extended into the left side of sacral bone (Figures 2(a) and 2(b)). The large mass showed low intensity on T1-weighted images and high intensity on T2-weighted images and was enhanced by contrast agent (Figure 2(b)).

A contrast-enhanced CT suggested the existence of the tumor thrombus of IVC (Figure 3).
The tumor cells are small and round shaped and have abundant glycogen.

IVC has completely vanished (Figure 6). In addition, we performed 3 cycles of chemotherapy. 4 years after the treatment, coin lesion of the left upper lung appeared (Figure 7).
Four years after the treatment, coin lesion in the left upper lung appeared.
