Presentation
Pain on the plantar surface of the right foot when walking, especially on the first step of the day.
Patient Data
Well-defined lytic lesion with central calcification (cockade sign) noted in the right calcaneum, no cortical disruption. Typical appearance of a calcaneal intraosseous lipoma.
Case Discussion
Intraosseous lipomas are relatively rare benign fatty tumors.
On plain radiographs, they are seen as well-defined lytic lesions, and a thin sclerotic rim may be noted. The lesion may present with either central necrosis or central calcification, the latter is known as a cockade image.
In the present case, the finding is likely to be incidental, as the clinical presentation is classic of plantar fasciitis.
