Proceedings of the European Society of Musculoskeletal Radiology (ESSR) training module, Antwerp, 20-21.01.05 - Part two: Bone tumors. Benign bone lesions: Characteristic imaging features

Benign bone lesions are a fairly common finding In radiology practice. Often, the combination of patient's age and plain radiographic findings are sufficient for diagnosis and obviates the need for further imaging. Generally the following parameters should be assessed in the evaluation of a bone lesion: clinical features, age of the patient, location, size, pattern of bone destruction, cortical involvement, zone of transition, sclerotic margination and matrix calcification. Cross sectional imaging, such as CT or MRI complements radiography, especially in complex anatomical sites. This article reviews the spectrum of clinical and imaging appearances of the most common benign bone tumors.
