case_images: (a-c) Computer-enhanced tomography showing local bony expansion and destruction of the right sacrum and iliac crest, with areas of low-density liquefied necrosis within, and disappearance of the right sacroiliac joint space. CT showed an abundant blood supply of the tumor.

case_images: Computer-enhanced tomography showed local bony expansion and destruction of the right sacrum and iliac crest, with areas of low-density liquefied necrosis within, and disappearance of the right sacroiliac joint space (Figures 1a-c).
case_images: MRI showed a tumor of the right sacrum and the ilium boundary was still clear, the size of which was about 63 * 91 * 107 mm.

case_images: The lesion broke through the bone cortex and infiltrated into the adjacent tissue space, with a mild irregular response zone around the lesion (Figure 2).
case_images: Imaging of the abdominal aorta shows the blood supply of the lesion came from the internal iliac artery.
