case_images: X-ray demonstrating the large nidus and the preservation of the proximal epiphysis. The important swelling of the fourth toe is well demonstrated.

case_images: fig1
case_images: The physis remained intact (Figure 1).
case_images: T2-weighted image on MRI, showing the sclerotic nidus hyposignal and the surrounding inflammation of the soft tissues around (hypersignal).

case_images: fig2
case_images: The MRI showed a hyposignal center of the distal end of the third phalanx of the fourth toe with surrounding inflammatory response and edema (Figure 2).
case_images: Gadolinium-enhanced T1-weighted images on MRI, showing the relative avascular nidus surrounded by hypervascular inflamed tissues.

case_images: fig3
case_images: The injection of gadolinium shows an increase of the signal in T1 around a more avascular center (Figure 3).
case_images: Histologic analysis demonstrating the characteristic pink-staining osteoid in a fibrovascular stroma (H&E staining, x300).

case_images: The specimen was sent as such for histologic examination and the diagnosis was confirmed (Figure 4).
case_images: (a) X-ray demonstrating the lyophilized bone graft three week after the intervention. (b) X-ray demonstrating the complete incorporation and remodeling of the graft one year after the intervention.
