This case emphasizes that radiographic changes, although not diagnostic, can be characteristic and highly suggestive of a disease process especially a benign or malignant tumor. Radiographic changes that suggested the possibility of a malignant process in this case included ill-defined margins of the lesion; bone production within the lesion, especially interdentally at the alveolar crest; widening of the periodontal ligament space around tooth roots within the lesions; and perpendicular bony striae extending outward from the surface of the bone (sun-ray effect). THese changes are not specific for a malignant process: however, when coupled with the clinical history, the probability of malignancy is high. Failure of recognition is considered the greatest problem in malignancy of the oral cavity. Clinicians should consider every abnormal condition as suspicious unless there are valid reasons for ruling out cancer.
该病例强调，影像学改变虽不具有诊断性，但可能具有特征性，且强烈提示某种疾病过程，尤其是良性或恶性肿瘤。在此病例中提示可能存在恶性病变过程的影像学改变包括：病变边界不清；病变内有骨质生成，尤其是牙槽嵴处牙间隙内；病变内牙根周围牙周膜间隙增宽；以及从骨表面向外延伸的垂直骨纹（日光放射状表现）。这些改变并非恶性病变过程所特有：然而，结合临床病史时，恶性的可能性就很高。认识不足被认为是口腔恶性肿瘤最大的问题。临床医生应将每一个异常情况视为可疑，除非有充分理由排除癌症。
