Heterogeneous, oval mass with variable areas of fat density in the lower left abdominal/upper pelvic wall, predominantly within the subcutaneous tissues but with relatively broad contact of the lower rectus abdominis musculature. Axial image series is incomplete.
Case Discussion
Biopsy-proven myxoid liposarcoma of the body wall. The fact that the mass is predominantly soft tissue density and within the body wall raises the concern of either a malignant mesenchymal mass or a benign desmoid tumor. The presence of at least some variable fat density can help favor a liposarcoma variant.
