Tumors and Tumor-Like Lesions

The purpose of this chapter is to provide knowledge about tumors that affect temporomandibular joint (TMJ) function. Because of this, details on tumor biology, behavior, and treatment will not be discussed. Tumors and pseudotumors can mimic more common non-neoplastic conditions given that pain and impairment are common features. Focus will therefore be on these aspects and on imaging of the most prevalent, although rare, TMJ tumors.
