Cockade sign (intraosseous lipoma)

The cockade sign is a classic appearance of an intraosseous lipoma of the calcaneus which presents as a well-defined lytic lesion with a central calcification resembling a cockade. 

It is named after a cockade, which is a badge, usually in the form of a rosette or knot, generally worn on the hat.

Bone tumours

The differential diagnosis for bone tumours is dependent on the age of the patient, with a very different set of differentials for the paediatric patient.
