Abstract
OBJECTIVES
To illustrate characteristic features of adenomatoid odontogenic tumour (AOT) on CBCT.
METHODS
The archived CBCT and panoramic radiographs of eight patients histopathologically diagnosed as AOT were analysed. The radiographic features displayed on both radiographic images were carefully described and compared.
RESULTS
All eight AOT cases presented as unilocular and well-demarcated lesions on both CBCT and panoramic images. CBCT images displayed three-dimensional interpretation of AOT lesions, especially the detailed intralesional radiopacities. Numerous discrete radiopaque foci scattered in the lesion with evident contrast to the radiolucent background could be considered as one of the characteristic features of AOT on CBCT.
CONCLUSIONS
Compared with panoramic radiography, CBCT seems to possess better potential in diagnosing AOT.
摘要
目的
展示 CBCT 下腺牙源性肿瘤（AOT）的特征。
方法
分析了 8 例经组织病理学诊断为 AOT 的患者的 CBCT 和全景片。仔细描述并比较了两种影像学图像上显示的放射学特征。
结果
所有 8 例 AOT 病例在 CBCT 和全景图像上均表现为单房性、边界清楚的病变。CBCT 图像对 AOT 病变进行了三维解读，尤其是对病变内的详细不透射线区域。病变内散在着大量离散的不透射线灶，与透亮背景形成鲜明对比，这可被视为 CBCT 下 AOT 的特征之一。
结论
与全景片相比，CBCT 在诊断 AOT 方面似乎具有更大的潜力。
