Lipoma intraóseo del calcáneo: un hallazgo radiológico infrecuente. Un caso clínico

Abstract

Objective

Intraosseus lipomas are an uncommon pathological entity. Its prevalence, however, is believed to be underestimated. We present a clinical case seen in a medical center consultation.

Clinical case

We report the case of a 57-year-old man without noteworthy pathological or family history, who consults at his health center due to periodic mild mechanical right heel pain during the past year.

Results

A simple imaging study of the affected foot was requested, which revealed a well-defined osteolytic lesion with a thin, linear sclerotic margin and a central calcification, without cortical disruption or involvement of adjacent soft tissues, exhibiting a nonaggressive radiological appearance. This image is referred to as a “bull's eye” or “cokade” and is suggestive of an intraosseous lipoma. The diagnosis was confirmed with the performance of magnetic resonance imaging.

Conclusion

The nonaggressive characteristics of this disease guides towards conservative management of intraosseus lipoma, reserving invasive surgical options only in case of complications or increased fracture risk.
