Lingual mandibular bone defects, also known as Stafne bone cavity (SC), are unilateral asymptomatic radiolucencies, generally seen in the mandibular angle, below the inferior alveolar canal. Although panoramic radiographies normally offer enough information to make a correct diagnosis, additional studies are often required, especially in atypical cases. The present report describes an atypical presentation of a Stafne's bone cavity in a 78 years-old male patient. In this particular case, an asymptomatic and radiolucid lesion was observed during a routine dental examination. The computed tomography (CT) showed an involvement of both lingual and buccal mandibular plates producing a tunnel-like lesion. No history of mandibular trauma or surgery was refered. An additional magnetic resonance imaging (MRI) was made to discard submandibular gland pathology and to confirm the diagnosis. Since SC is asymptomatic and nonprogressive, a conservative approach based in clinical and radiological follow-ups was considered to be the most suitable treatment option. Key words:Stafne bone cavity, lingual mandibular bone defect, case report.
舌侧下颌骨缺损，也称为斯塔夫内骨腔（SC），是单侧无症状的透射区，通常见于下颌角，在下牙槽神经管下方。尽管全景X线片通常能提供足够信息以做出正确诊断，但通常还需要进行其他检查，尤其是在非典型病例中。本报告描述了一名78岁男性患者斯塔夫内骨腔的非典型表现。在这个特殊病例中，在常规牙科检查时发现了一个无症状的透射性病变。计算机断层扫描（CT）显示舌侧和颊侧下颌骨板均受累，形成隧道样病变。患者无下颌骨外伤或手术史。另外进行了磁共振成像（MRI）以排除下颌下腺病变并确诊。由于SC无症状且不进展，因此基于临床和影像学随访的保守治疗方法被认为是最合适的治疗选择。关键词：斯塔夫内骨腔；舌侧下颌骨缺损；病例报告
