Soft-tissue recurrence of osteosarcoma: ultrasound findings

The authors describe a 26-year-old woman with soft-tissue recurrence of osteosarcoma, which presented as focal soft-tissue swelling after limb salvage surgery and insertion of a metallic endoprosthesis. Because of the clinical presentation, ultrasonography was performed. The characteristic ultrasonographic pattern of soft-tissue tumours is summarized here, and the role and limitations of ultrasonography in this situation are discussed.
