Bone tumors and tumorlike conditions: analysis with conventional radiography.

The approach to the radiographic diagnosis of bone tumors consists of analyzing the lesion in an organized fashion, with attention to the specific radiographic features of tumor location, margins, and zone of transition; periosteal reaction; mineralization; size and number of lesions; and presence of a soft-tissue component. Patient age is also an important clinical factor in the diagnosis of bone tumors, because various lesions have predilections for specific age groups.
