Imaging of Jaw Lesions Related to Multiple Myeloma - Abstract
Multiple myeloma is a hematologic malignancy in which the bones are usually affected. The aim of this study is to describe the imaging of jaw bone lesions of patients with multiple myeloma, as reported in the literature. Nearly one third of the patients diagnosed with multiple myeloma present bone lesions in the jaws, and these lesions may assume a variety of radiographic aspects. Lytic lesions named ‘punched-out’ lesions are the most common observed features, and may appear as solitary or multiple lesions. The mandible is usually more affected than the maxilla, and the body, angle and ramus of the mandible are the most affected regions. Orofacial and dental pain, swelling, dental displacement, and root resorption may be present. Screening imaging of jawbones is necessary to detect bone lesions related to multiple myeloma. The extension and relationship of the jaw lesions with the adjacent structures may be evaluated through different imaging tools.
