An intra-osseous lipoma is an uncommon benign bone lesion, most frequently identified in long bones, but also seen in the calcaneum in up to 10% of cases.
Intra-osseous lipomas are located almost exclusively within the medullary cavity. They are composed of mature adipocytes.
In many cases it is found incidentally, although they can be symptomatic.
Plain film usually diagnostic with a well defined round lucent lesion with a thin sclerotic rim and a central focal area of sclerosis – sometimes referred to as a ‘bull’s eye’.
