A 13-year-old male patient with pain in the right leg. a. AP radiograph of the left leg. A geographical metaphyseal lytic lesion (arrow) having a thin sclerotic rim suggestive of a benign lesion. b STIR coronal image shows a well defined hyperintense eccentric metaphyseal lesion in right tibia. c MRS shows choline peak at 3.2 ppm. d HNE 200× shows lobule of myxoid material with stellate cells displaying hypercellularity at the periphery along with giant cells diagnostic of chondromyxoid fibroma
