From the pseudolipoma to lipoma: staging of the typical radiological appearances. Pictorial essay.

Duzgun Yildirim, Cuneyt Tamam, Baki Ekci


Lipomas are benign mesenchymal tumors, which accounts for 50% of soft tissue tumors. Although the etiopathogenesis has not yet been fully understood, it is known that lipomas developed at a rate of 1% in the related localizations after traumas. Trauma initiates inflammatory reactions in fatty tissue and these can be the trigger mechanism for the development of lipomas. In this pictorial essay the objective was to present the imaging findings associated with the process of lipomas development. “The phases of lipomas formation” was schematized based on these data.
