AP radiograph of the knee at presentation (left) shows faint periostitis of the distal femur and proximal tibia and fibula. There is a metaphyseal lucency present along the proximal portion of the medial aspect of the tibial metaphysis (Wimberger corner sign). Repeat radiograph obtained 2 months later while on therapy (right) shows dense periostitis of the bones with resolution of the lesion previously seen on the proximal medial tibial metaphysis.
