A patient presented with a draining sinus tract on the lingual alveolus of the posterior mandibular ridge. The source of the sinus tract was not readily apparent. Radiographs created the impression that a lesion of unusual and possibly metastatic origin might be involved. Comprehensive diagnostic tests were ordered, but the source of the lesion remained obscure until a surgical exploration was performed.
一名患者在下颌后牙牙槽嵴的舌侧牙槽出现了一个引流窦道。窦道的来源并不明显。X光片显示可能存在一个起源异常且可能为转移性的病变。于是安排了全面的诊断检查，但在进行手术探查之前，病变的来源一直不明。
