摘要
目的:分析颌骨成釉细胞瘤与牙源性角化囊性瘤的CT表现,提高对其诊断水平。方法:回顾性分析经手术病理证实的15例成釉细胞瘤及21例牙源性角化囊性瘤的CT表现,观察病变的分布和形态特征。结果:成釉细胞瘤以多房型多见,颊舌侧的膨胀更明显,且多向唇颊侧膨胀,常见邻牙牙根截断状吸收。牙源性角化囊性瘤以单房分叶型多见,易沿下颌骨长轴生长,少有牙根吸收。结论:成釉细胞瘤与牙源性角化囊性瘤各自具有一定的CT特点,CT对于二者的鉴别诊断具有重要价值。
Purpose： To improve the CT diagnostic accuracy of ameloblastomas and keratocystic odontogenic tumors of the jaw by analyzing their CT manifestations. Methods： CT features of 15 cases of ameloblastomas and 21 cases of keratocystic odontogenic tumors of the jaw were retrospectively reviewed,the location and configuration of the lesions were observed.Results： Ameloblastomas mainly appeared as multilocular and usually produced more marked buccolingual expansion and root resorption of the adjacent teeth than keratocystic odontogenic tumorsdid. Keratocystic odontogenic tumors mainly appeared as unilocular lesions with a scalloped outline and had the tendency to grow along the long axis of the mandible. Conclusion： There are some characteristic imaging findings for ameloblastomas and keratocystic odontogenic tumors of the jaw, so the differential diagnostic value of CT scanning is with significance.
