“…17 Cases described as radiopaque or mixed in panoramic images represented maxillary sinus opacification. [18][19][20][21][22] Radiographic imaging typically revealed a locally destructive pattern, with illdefined borders and tumour extension to adjacent structures in many instances. This tumour extension often resulted in difficulty establishing the primary location of the neoplasm.…”

“…The only true mixed (radiopaque and radiolucent) lesion present in a periapical image represented a myeloid sarcoma in which the mandibular trabeculae were more radiopaque with areas of patchy radiolucencies 17 .

Background: This systematic review aimed to investigate the radiological features of lymphomas and leukaemias affecting the jaws.Methods: A systematic literature review was conducted using the electronic databases of PubMed, Web of Science and Scopus. Articles that contained sufficient radiographic examinations (periapical, panoramic or computed tomography images) for individual cases were included. Additionally, either immunohistochemical or molecular confirmation was required prior to inclusion. Three authors evaluated and described the image quality and radiological features.Results: From an initial 1079 articles screened, 129 cases were included, containing 88 tomographic, 76 panoramic and 26 periapical examinations. The quality of the majority of images was sufficient for evaluation. Diffuse large B-cell lymphoma, Burkitt lymphoma, leukemic infiltration, plasmablastic lymphoma and extranodal Natural killer (NK)/T-cell lymphoma, nasal type were the most common subtypes. Involved teeth presented with mobility in 37.2% of the cases and a provisional diagnosis of inflammatory/infectious dental disease was considered in 49.2% of cases. Computed tomography exams were available for 76% of the cases, with most presented with an osteolytic lesion with ill-defined borders. Periosteal reactions were uncommon. Conclusion:Lymphoma/leukaemia infiltrates of the jaw bones are usually of highgrade subtypes and rarely present with periosteal reactions.
