Stafne's bone defect (SBD) is an uncommon bone alteration that affects the mandible and usually presents as an asymptomatic radiolucency located in the posterior region of body or angle of the mandible, below the alveolar canal. Although clinical and radiographic features are more often sufficient for the diagnosis, other lesions and bone alterations have been described in the differential diagnosis and may lead to a misinterpretation and an incorrect diagnosis. Herein, we report a case of an 89-yearold man with metastatic prostate cancer to multiple bones, presenting an asymptomatic solitary well-defined radiolucent image on the right side of the posterior body of the mandible, in close contact with its inferior border. A bone depression was confirmed by computed tomography scans of the mandible and a metastatic inclusion was ruled out by bone scintigraphy with a final diagnosis of SBD. The aim of this report was to highlight the importance of differentiating SBD from metastases in cancer patients and to reinforce the usefulness of multiple imaging modalities in the differential diagnosis of SBD.

斯塔夫内骨缺损（SBD）是一种罕见的影响下颌骨的骨质改变，通常表现为位于下颌骨体部或角部后方、牙槽管下方的无症状性透射区。尽管临床和影像学特征通常足以做出诊断，但在鉴别诊断中也描述了其他病变和骨质改变，可能导致误诊和错误诊断。在此，我们报告一例89岁男性，患有多处骨转移的前列腺癌，在下颌骨体部右侧后部出现一个无症状的、边界清晰的孤立性透射影像，与下颌骨下缘紧密相邻。通过下颌骨计算机断层扫描证实为骨凹陷，骨闪烁显像排除了转移瘤，最终诊断为SBD。本报告的目的是强调在癌症患者中将SBD与转移瘤相鉴别的重要性，并强化多种影像学检查方法在SBD鉴别诊断中的作用。斯塔夫内骨缺损、下颌骨、凹陷、转移瘤、影像学检查方法
