摘要
目的 :探讨螺旋CT诊断颌骨牙源性囊肿与造釉细胞瘤的价值。材料和方法 :回顾性分析经手术和病理证实的13例牙源性囊肿和 7例造釉细胞瘤的螺旋CT表现 ,观察病变形态和结构特征。结果 :角化囊肿 5例 ,含牙囊肿 6例 ,根尖囊肿 2例 ,造釉细胞瘤 7例。牙源性囊肿主要表现为单房型 ,边缘清楚伴硬化。造釉细胞瘤表现为多房型或单房分叶状 ,膨胀性生长伴邻近骨壁破坏。结论 :牙源性囊肿与造釉细胞瘤多具有特征性CT表现 ,螺旋CT扫描能提供病变的定位、定性和范围可靠信息。
Purpose: To evaluate the diagnostic value of spiral CT in ondontogenic cysts and ameloblastomas. Materials and Methods: Spiral CT features of ondontogenic cysts (n=13) and ameloblastomas (n=7), which were proved by surgery and pathology, were retrospectively studied, and the configuration and structure of the lesions were observed. Results: The ondontogenic cysts, including keratotic cyst (n=5), dentigerous cyst(n=6) and periapical cyst(n=2) , mainly displayed unilocular in shape and distinct margin with sclerosis.Ameloblastomas mainly displayed multilocular or lobulated in shape and markedly expanded growth with disruption of the adjacent cortex. Conclusion: Most lesions of ondontogenic cysts and ameloblastomas have characteristic manifestation in CT. Spiral CT can provide reliable information about site,qualitative analysis and extension of lesion as well.
