This report presents a rare case of ameloblastoma with histopathologic and radiographic calcification, including 3-dimensional cone-beam computed tomographic (CBCT) images. A 22-year-old woman had hard swelling on the right mandible. Panoramic and CBCT images showed multilocular radiolucencies with internal calcification foci in the right mandible. Three-dimensional images clearly showed varying-sized radiopacities within the lesion from various angles. A histopathologic examination showed central squamous differentiation and more densely packed peripheral palisading ameloblastic cells. Many areas of keratin pearls and calcifications were also seen. Four previous reports have described 5 cases of ameloblastoma showing histopathologic calcification. This might be the first report to present the calcification of ameloblastoma on panoramic and CBCT images, especially on 3-dimensional images.
本报告介绍了一例罕见的伴有组织病理学和影像学钙化的成釉细胞瘤病例，包括三维锥形束计算机断层扫描（CBCT）图像。一名22岁女性右侧下颌骨出现硬性肿胀。全景和CBCT图像显示右侧下颌骨有多房性透射区，内部有钙化灶。三维图像从不同角度清晰显示病变内大小不一的不透光区。组织病理学检查显示中央鳞状分化，外周成釉细胞排列更紧密。还可见许多角化珠和钙化区域。此前有四份报告描述了5例显示组织病理学钙化的成釉细胞瘤病例。这可能是第一份展示成釉细胞瘤在全景和CBCT图像上钙化情况的报告，尤其是在三维图像上。
