PDFAbstract
Objective To assess the CT and MRI imaging features of liposarcoma. Methods 25 cases of liposarcoma proved pathologically were retrospectively studied.All patients underwent CT or MRI examination before and after intravenous administration of contrast agent.Because this study was a retrospective review,complete imaging data were not available for each patient. Results 13 of Myxoid liposarcomas consists of myxoid matrix as the predominant component and small amounts of mature fat,showed light enhancement or enhancement with inhomogeneous and flocculent strengthen.9 of Welldifferentiated liposarcomas showed masses with fat-density and fewer enhancement.2 of Dedifferentiated liposarcoma was demonstrated as fat-density containing soft tissue,showed moderate to the marked homogenous enhancement in the non-fatty areas.1 of Roundcelled liposarcoma displayed as soft tissue mass containing no fat,showed inhomogeneous and strong enhancement.There is not pleomorphic liposarcoma in this study. Conclusion Different subtypes of liposarcomas exhibited varying CT and MRI features,depending on their histological components.
