When diagnosing<unk> , the preliminary radiologic workup should consist of radiography of the site of the patient's pain. However, computed tomography (CT) is often necessary to support clinical and plain radiographic findings suggestive of<unk>  and to better define the margins of the lesion for potential surgery. CT scans are best used for the further characterization of the lesion with regard to the presence of a nidus and matrix mineralization. MRI aids in the detection of nonspecific reactive marrow and soft-tissue edema, and MRI best defines soft tissue extension, although this finding is not typical of<unk> . Bone scintigraphy (bone scan) demonstrates abnormal radiotracer accumulation at the affected site, substantiating clinical suspicion, but this finding is not specific for<unk> . In many patients, biopsy is necessary for confirmation.
