Primary Rosai-Dorfman Disease of Bone: A Report of Two Cases

Figure 6

PA and oblique views of the left wrist from patient 2 demonstrate a lucent lesion with numerous internal septations in the distal radial metaphysis and epiphysis. There is marked thinning of the cortex along the radial margin of the distal radius (arrowhead). The cortical thinning is more pronounced and the lesion more aggressive in appearance than in patient 1.
