Overview
CT imaging is crucial for the diagnosis of liposarcoma. CT scan may detect regions of lipid and non-lipid components that correlate with histological subtypes of liposarcoma. CT imaging may demonstrate the size, location, and depth of a liposarcoma, as well as lymph node involvement and distant metastasis. CT findings may be correlated with the histopathological subtype.
CT Scan
- A CT image commonly detects areas of focal or diffuse infiltration of lipid and non-lipid components.
- The appearance and morphologic relationship between the lipid and non-lipid components of a liposarcoma on CT scan frequently help in identifying the specific histologic subtype of liposarcoma.[1]
- CT scan also determines the size and depth of the tumor, stage of the disease, presence of lymphadenopathy, and evidence of distal metastasis.[2]
CT Findings According to the Liposarcoma Subtype
| Subtypes | Density | Margins | Fat Content | Nodular muscle-density area in tumor | Calcifications | Necrotic or cystic areas |
| Atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) | Fat | Smooth regular | > 65% | ++ | Few/none | + |
| Dedifferentiated liposarcoma (DDL) | Mixed | Rough irregular | 30-60% | +++ | Few/none | ++ |
| Myxoid/round cell liposarcoma (ML/RCL) | Mixed | Rough irregular | 25-50% | + | Common | +++ |
| Pleomorphic liposarcoma (PL) | Soft tissue | Incomplete irregular | 6-25% | + | Few/none | + |
| Mixed-type liposarcoma | Mixed | Smooth regular | 30-60% | ++ | Common | + |
