Investigation of the computed tomographic appearance of canine acanthomatous ameloblastoma to describe characteristic imaging features of this neoplasia within the jaw bone.
Retrospective evaluation of epidemiological data and imaging results in 70 dogs with histologically confirmed acanthomatous ameloblastoma. In 52 dogs a computed tomography study was available, while radiographs of the rostral maxilla or mandible were available in 18 dogs.
The neoplasia was most commonly located in the rostral parts of the mandible. Dogs of medium and large breeds were most commonly affected with no apparent breed predisposition. A bimodal age distribution could be demonstrated. 19% of the dogs were under 5 years of age. In 45 (86%) of 52 dogs examined by computed tomography osteolysis was present, which in some cases was extensive. An expansile bone destruction of the dental alveolar cavity with osteolysis of the apical border was recognized as the characteristic computed tomographic feature.
Canine acanthomatous ameloblastoma commonly displays a characteristic computed tomographic appearance, which in combination with histopathological confirmation helps in the diagnosis of this tumour.
研究犬棘皮瘤型成釉细胞瘤的计算机断层扫描表现，以描述颌骨内这种肿瘤的特征性影像学特征。
对70只经组织学确诊为棘皮瘤型成釉细胞瘤的犬的流行病学数据和影像学结果进行回顾性评估。52只犬有计算机断层扫描研究资料，18只犬有上颌前部或下颌骨的X线片。
肿瘤最常见于下颌前部。中型和大型犬最常受影响，无明显品种易感性。可显示出双峰年龄分布。19%的犬年龄在5岁以下。在52只接受计算机断层扫描检查的犬中，45只（86%）存在骨质溶解，在某些情况下范围广泛。牙槽腔的膨胀性骨质破坏伴根尖边缘骨质溶解被认为是特征性计算机断层扫描表现。
犬棘皮瘤型成釉细胞瘤通常表现出特征性的计算机断层扫描表现，结合组织病理学确诊有助于该肿瘤的诊断。
