Long-term follow-up of 15 patients with non-metastatic Ewing's sarcoma and a skip lesion

Figures & data

Figure 1. Ewing's sarcoma of the left humerus, demonstrating the primary and skip lesions on both radiographs (A) and MR scan (B).

Figure 2. Ewing's sarcoma of the fibula with a skip lesion on the shaft of the tibia, not evident on conventional radiographs (A) but clearly seen on the MR scan (B).
