Imaging of Gaucher disease

Figure 8 Endosteal scalloping. Frontal radiograph (A) of the femurs shows an area of rounded thinning of the medial cortex of the left femur (arrow). Coronal out of phase image of the femurs in the same patient (B) shows low signal intensity in that same area due to expansion of the medullary cavity due to infiltration. The thinning of the cortex is less apparent on magnetic resonance than on radiography.
