【摘要】 目的探讨X线与CT检查对成釉细胞瘤的诊断价值。方法回顾性分析15例经病理证实的成釉细胞瘤的X线与CT表现,观察病变的形态和结构特征。结果 15例患者中,10例位于下颌骨磨牙区及升支部,3例位于上颌骨,2例位于下颌体部。X线影像多房型9例,单房型3例,蜂窝型2例,局部恶性征型1例;CT表现:病变呈多房型9例,单房型3例,蜂窝型3例。其中多房型者7例边缘呈分叶状,3例可见不完全骨性分隔。病变以向唇颊侧膨胀为主,边界较清;病变区密度不均,CT值范围为9.6～30.4Hu,平均20.2Hu。结论 X线与CT检查对成釉细胞瘤的诊断及鉴别诊断有重大价值。更多还原

【Abstract】 Objective To study the value of X-ray and CT examination in the diagnosis of ameloblastoma of the jaw.Methods X-ray and CT features of ameloblastomas,which were proved by pathology,were retrospectively studied,and the configuration and structure of the lesions were observed.Results Among 15 the cases,10 lesions located in molaramus region of mandible,3 lesions located in body of mandible,2 lesions located in maxilla.On X-ray images ,the series of unicystic ameloblastoma were composed of 9 cases with multilocular appearance and 3 cases with unilocular appearance,2 cases with honeycomb.On CT images,9 lesions were multilocular,3 cases with unilocular appearance,3 cases with honeycomb.7 cases showed cortical perforation,3 had soft tissue masses;CT value of the lesions ranged from 9.6 Hu to 30.4 Hu(mean 20.2Hu).Conclusion The application of X-ray and CT could improve the diagnostic accuracy of ameloblastomas of the jaw.更多还原
