Skip metastases in Ewing's sarcoma: a report of three cases.
The accurate pre-operative staging of all potentially malignant tumours of bone is essential. We report three cases of Ewing's sarcoma of bone in which MR imaging identified skip metastases not visualized on either contemporary radiographs or bone scintigraphy. The implications for patient management and possible reasons for the other imaging modalities failing to reveal the skip metastases are discussed.
