On T1-weighted sequences the lesions were of low signal intensity (Figure 3) and on post contrast T1-weighted images the lesions presented with high signal intensity with small areas of intermediate signal intensity (Figure 4).
Post contrast coronal T1-weighted MRI shows a heterogeneous increased signal at the left iliac bone (arrows) and at the left sacral wing.

On STIR images the tumor displayed a high signal intensity from the lesions (Figure 5).
Postoperative post-contrast coronal T1-weighted MR image demonstrates diminution of the extension and the enhancement of the tumor at the left iliac bone (arrows) and at the left sacral wing (curved arrow).
