Overview
CT Scan
- Imaging findings of liposarcoma are frequently characteristic.
- Focal or diffuse areas of fat associated with nonlipomatous components are commonly detected on computed tomographic or magnetic resonance images.
- The appearance and morphologic relationship between these areas frequently allow identification of the specific histologic subtype of liposarcoma.
CT Findings According to the Liposarcoma Subtype
| Subtypes | Density | Margins | Fat Content | Lymph Nodes | Calcifications | Necrosis |
| 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 | + |
| Table adapted from CT Manifestations in Histologic Subtypes of Retroperitoneal Liposarcoma[1] | ||||||
