RADIOLOGIC AND PATHOLOGIC ANALYSIS OF SOLITARY BONE LESIONS

The margin or interface between tumor and bone (cortical or cancellous) that is displayed radiographically is a zone of cellular activity. Its radiographic appearance represents the summation of bone lysis (osteoclastic activity) and production (osteoblastic activity). This activity and the radiographic details of the resultant margin are an index of the biologic activity of a lesion. The anatomic site and extent of the lesion can be assessed by radiographs and special imaging techniques. Careful analysis of these patterns, when integrated with clinical data, enhances diagnosis, patient management, and therapy.
