Imaging characteristics of neoplasms and other lesions of the jawbones: part 2. Odontogenic tumor-mimickers and tumor-like lesions.

Obtaining an accurate diagnosis of odontogenic tumor-mimickers (nonodontogenic lesions masquerading as odontogenic lesions) and tumor-like lesions of the jawbones can be difficult and requires a multidisciplinary approach. Lack of familiarity with these disease processes may lead to uncertainty and errors in diagnosis, which increase the possibility of errors in treatment. Radiologists should be aware of the imaging appearances of lesions affecting the jawbones in order to provide a complete differential diagnosis and to guide clinicians in proper patient treatment. The morphologic characteristics of tumors and tumor-like lesions of the jawbones may provide key diagnostic information regarding the aggressive or nonaggressive biologic behavior of such lesions. In addition to imaging findings, thorough physical examination and, often, histologic analysis of biopsy specimens are required.
