Pelvis radiograph showed a large osteolytic lesion over right iliac bone near sacroiliac junction (white arrows) (A). MRI revealed a 9.6 × 9.4 × 9.0 cm bilobular huge tumor mass arising from right iliac wing with bony destruction and significant soft tissue extension (white arrows) (B to E). 99mTc-MDP BS showed mildly hot areas at right iliac bone with a large, round cold area (black arrows) (F). B: axial T1-weighted image with contrast enhancement. C: axial T2-weighted image. D: coronal fat-suppressed (FS) T2-weighted image with contrast enhancement. E: coronal short tau inversion recovery (STIR) images.
