a-f A 4.8-year-old male patient (case C). The X-ray and CT results show right iliac bone destruction, with a low-density shadow, a blurred edge and a small periosteal reaction. Surrounding muscle tissue is swollen (a, b). MRI shows equal long T1 and abnormal T2 signals with cortical damage, surrounding soft tissue thickening and swelling, with long T1 and T2 signals (c, d). Six months after the operation, the X-ray results show partial bone growth in the lesion (e). The histological results suggest eosinophilic infiltration (f) (white arrows indicate the site of the lesion)
