An unusual case of a large complex odontoma with an associated impacted tooth is presented. Odontomas are hamartomatous growths of enamel, dentin, cementum and pulp tissue. Although they are usually tooth-sized or smaller, occasionally, the complex variant can exhibit considerable growth, as was seen in the case presented here. It occupied most of the maxillary sinus and displaced the floor of the orbit and the medial and posterior walls of the left maxillary sinus. Panoramic radiographs, as well as axial and coronal CT studies, showed the extent of the lesion in various dimensions. A differential diagnosis of various calcifying tumors was formulated on the basis of these findings. The lesion was surgically excised, and histologic analysis confirmed the radiographic impression. Although odontomas of this magnitude are rare, this case demonstrates the value of imaging, radiographic histopathologic diagnosis and surgical treatment planning prior to any definitive treatment.
本文介绍了一例罕见的伴有阻生牙的大型复杂牙瘤病例。牙瘤是由釉质、牙本质、牙骨质和牙髓组织构成的错构瘤性生长物。尽管它们通常与牙齿大小相当或更小，但偶尔复杂型牙瘤会呈现出显著的生长，如此例所示。它占据了大部分上颌窦，并使眶底以及左上颌窦的内侧壁和后壁移位。全景X线片以及轴向和冠状CT研究显示了病变在各个维度上的范围。基于这些发现，对各种钙化性肿瘤进行了鉴别诊断。病变通过手术切除，组织学分析证实了影像学诊断。尽管如此大的牙瘤很少见，但该病例展示了在进行任何确定性治疗之前，影像学、放射学组织病理学诊断和手术治疗规划的价值。
