MR imaging of transarticular skip metastases from distal femoral osteosarcoma.
We describe a case in which magnetic resonance (MR) imaging of a distal femoral osteosarcoma showed transarticular skip metastases in the proximal tibia. These lesions were not found by conventional radiography, bone scintigraphy, or CT. Since detection of transarticular skip metastases has an important influence on surgical management, MR imaging of metaphyseal osteosarcomas should always include the bone on the opposite side of the joint.
