Abstract

The diagnosis of a bone tumour is based on clinical findings, the age of the patient, the anatomic location of the lesion, its radiologic appearance, and if imaging does not allow for a specific diagnosis, its histopathologic features. Radiography remains the initial imaging modality for evaluation of the location of the lesion with respect to the longitudinal and axial planes of the involved bone, for estimation of its biologic activity by analysing the patterns of bone destruction and periosteal response, and for the depiction of matrix mineralisation. CT is typically used to obtain “radiographic” information in regions of complex skeletal anatomy such as the skull, spine, pelvis and shoulder girdle. MR imaging is best suited to determine the local extent of a bone tumour (local staging), but can also be helpful to narrow the differential diagnosis in specific lesions such as cysts and cartilage-forming tumours. With a clear emphasis on conventional radiography, this course will review the basic imaging features of the most common benign and malignant bone tumours. Important radiographic findings, such as bone destruction patterns, types of periosteal reactions and matrix mineralisation, will be explained step by step in correlation with histopathology as well as advanced imaging techniques.
