Ameloblastoma is a fairly common and highly aggressive odontogenic tumor of epithelial origin. It is primarily seen in adults in the third to fifth decade of life. Radiographically, it appears as an expansile lucency with thinned and perforated cortices. It is known to cause root resorption. Because it shares common radiographic features with other lesions, definitive diagnosis is made through histopathologic analysis. This case demonstrates the use of cone beam computed tomography in the differential diagnosis of a large plexiform ameloblastoma in a 29-year-old man. The extent of the lesion and the effect on adjacent structures can be discerned from the images. Additional features seen on these images can aid in the diagnosis. This imaging modality is also useful in surgical planning.
成釉细胞瘤是一种相当常见且具有高度侵袭性的上皮源性牙源性肿瘤。它主要见于30至50岁的成年人。在影像学上，它表现为具有变薄和穿孔皮质的膨胀性透亮区。已知它会导致牙根吸收。由于它与其他病变具有共同的影像学特征，因此通过组织病理学分析进行明确诊断。本病例展示了锥形束计算机断层扫描在一名29岁男性大型丛状成釉细胞瘤鉴别诊断中的应用。从图像中可以辨别病变的范围以及对相邻结构的影响。这些图像上看到的其他特征有助于诊断。这种成像方式在手术规划中也很有用。
