Abstract：
BACKGROUND: The purpose of the current study was to report on the clinical presentation and radiologic features of 155 cases of ameloblastoma (AB), representing a detailed, large, single-centre radiologic study.
METHODS: Histologically confirmed cases were reviewed over 11 years. Demographic and clinical data were retrieved from the patient\'s records. Radiologic information was analysed from available radiographs. The radiologic features of ABs were assessed according to the mean age of presentation and the mean duration of the lesion. The distinguishing radiologic features between adults/children and sex were also evaluated.
RESULTS: A statistically significant correlation existed between loss of border demarcation and advanced mean age. Multilocular lesions were markedly more common in adults compared to children. Multilocular ABs were associated with increased lesion duration and advanced mean age. Radiologic signs of reactive bony changes associated with the tumour presented at the highest mean duration of all bony effects. Bony expansion and cortical destruction were statistically correlated with lesion duration. Tooth impaction was more common in children. Some mandibular lesions reached a significant size, resulting in impingement of the maxillary sinus, zygoma, orbit and pterygoid plates.
CONCLUSIONS: Due to unfortunate healthcare access constraints, ABs grow to significant sizes and exhibit features not often reported in the literature. The findings of this analysis highlighted the radiologic features of ABs expressed through the mean age and duration of the lesion. This emphasises the significance of timely management of these lesions.

摘要：
背景：本研究的目的是报告155例成纤维细胞瘤（AB）的临床表现和影像学特征，代表一个详细的，大,单中心放射学研究。
方法：回顾了11年的组织学确诊病例。从患者记录中检索人口统计学和临床数据。从可用的X射线照片中分析放射学信息。根据出现的平均年龄和病变的平均持续时间评估ABs的放射学特征。还评估了成人/儿童和性别之间的放射学特征。
结果：边界分界缺失与高龄之间存在统计学上显著的相关性。与儿童相比，多房性病变在成人中明显更常见。多房性ABs与病变持续时间增加和平均年龄提前相关。与肿瘤相关的反应性骨变化的放射学征象在所有骨作用的平均持续时间最高时出现。骨扩张和皮质破坏与病变持续时间相关。牙齿嵌塞在儿童中更为常见。一些下颌骨病变达到明显的大小，导致上颌窦撞击，zygoma,眼眶和翼状体板。
结论：由于不幸的医疗保健准入限制，AB增长到显著的尺寸并且表现出文献中不经常报道的特征。该分析的结果强调了通过病变的平均年龄和持续时间表达的ABs的放射学特征。这强调了及时管理这些病变的重要性。
