Overview
MRI is the imaging test of choice for the diagnosis of liposarcoma. MRI findings may differentiate between the different subtypes of liposarcoma and help to assess distant metastasis.
MRI
- MRI findings for a well-differentiated liposarcoma include a mass with at least 75% of adipose content with thin irregular septa. [1]
- Other subtypes show less adipose content.
- Thick septa inside the mass is associated with a more malignant prognosis.
- For the dedifferentiated subtype, hemorrhage and necrosis may be observed inside the mass.
- The myxoid subtype may be associated with cystic imaging findings in aproximatelly 20% of cases. [2]
