Figure 6 (A-D): Rapidly-growing painful mass in the left arm in a 15-year-old girl. There was no history of trauma. Axial T1W MRI (A) shows moderate hyperintensity of the lesion (black arrows). Axial contrast enhanced fat-suppressed T1W MRI (B) shows rim enhancement of the lesion (large arrow). Sagittal fat-suppressed T2W MRI (C) shows hypointense areas at the periphery of the lesion (arrows) and edema in the surrounding soft tissues (arrowhead). Sagittal CT scan (D), performed on the same day as the MRI shows the characteristic rim ossifications (white arrows)
