Objective: The purpose of this study was to illustrate the subtypes of liposarcoma (LPS) and the significance of the nonlipomatous tumor components using multiple imaging modalities.
Conclusion: The subtypes of LPS with greater nonlipomatous soft-tissue components on imaging studies tend to show less differentiation and are usually more aggressive both histologically and clinically. Imaging plays an important role in the diagnosis, surveillance, and response assessment of LPS.
