From: Bilateral proptosis: an unusual primary presentation of scurvy—a case report
Anteroposterior radiograph of knee joint reveals metaphyseal dense bands in bilateral distal femoral metaphyses (white arrows) with adjacent proximal horizontal bands of radiolucency (open arrowhead) suggestive of zone of provisional calcification with Trummerfeld zones. Flaring at metaphyseal corners of distal femoral metaphysis (open arrows) suggestive of Pelkan spurs. Centrally lucent epiphysis with sharply marginated sclerotic rim (white arrowhead) (Wimberger ring sign). Similar findings also seen in bilateral proximal tibial physes. The findings are characteristic for scurvy
