Abdominal mass and weight loss

Patient Data

Age: 73
Gender: Male

Huge right-sided retroperitoneal mass - largely composed of fat, but also several soft tissue components.  The mass is displacing the right kidney anteriorly, as well as the liver and bowel anteromedially.

Case Discussion

Retroperitoneal liposarcoma is uncommon. It forms one of the spectrum of fat containing retroperitoneal masses, which range from benign to frankly and aggressively malignant lesions.

It contains both fatty and soft tissue elements and is often sizeable before presentation. They characteristically displace, rather than infiltrate adjacent structures.
