Lateral (a) and anteroposterior (b) views of plain radiography of the left heel showed an expansile sclerotic lesion in the calcaneum with cortical break and periosteal reaction.

In our institute, a plain radiography of the left heel was repeated and showed an expansile sclerotic lesion in the calcaneum with cortical break and periosteal reaction (Fig. 1).
On T1-weighted sagital ankle MRI imaging (a), the lesion was seen as low intensity with bone grafts. On T2-weighted imaging (b), the lesion was heterogeneously hyperintense with few foci of blooming in the central and peripheral parts. It showed a significant postcontrast enhancement in these parts too.

The lesion appears predominantly hypointense on T1-weighted imaging and heterogeneously hyperintense in T2/STIR (short-tau inversion recovery), with few foci of blooming in the central and peripheral parts and significant postcontrast enhancement in these parts (Fig. 2).
