ABSTRACT
Objective To investigate CT and MRI features of abdominal huge liposarcoma,and improve the preoperative diagnostic accuracy. Methods The CT and MRI findings of 1 7 cases with abdominal huge liposarcoma proved by operation and pathology were analyzed and correlated with pathologic subtypes retrospectively.Results In 17 cases,16 cases were located in retroperitoneal,1 case was located in the abdominal cavity.The average maximal diameter of the lesions was 17 cm.In all cases,main components of well differentiated liposarcomata (n=7) were fat density on CT and MRI,and enhanced slightly,3 cases were multiple lesions,1 case of sclerosing liposarcoma contained massive patchy calcification,1 case was fatless.Myxoid liposarcoma (n=5)were similar to cystic on CT and MRI features,enhanced with latticed or cloudy components slightly to moderately .Dedifferentiated liposarcoma (n=2)has both fat and soft tissue inside and the dividing line was clear.The soft tissue mass unevenly obviously enhanced.Mixed liposarcoma (n=3)had the imaging characteristics above different types,2 cases contained no fat composition.Conclusion Liposarcoma pathological subtype has diversity,and various subtypes have certain characteristic on CT and MRI imaging features.
