目的：??通过分析总结成牙骨质细胞瘤的临床及影像资料特征，以期提高临床医生对该病的诊断及鉴别。方法??回顾性总结分析14例成牙骨质细胞瘤患者的临床及影像资料。结果??14例成牙骨质细胞瘤患者就诊年龄11~58岁，中位年龄21.0岁，平均年龄27.6岁；男女各7例；好发于下颌骨；最常见的症状是颌骨肿胀和疼痛。特征性影像表现：与病变牙根融合的类圆形包块影，可见完整的包膜影像，与周围骨质分界清晰。肿瘤实质一般为团块状高密度影。根据肿瘤实质密度不同可分为均质型和非均质型。此外病变周缘常可见骨质增生硬化，下颌下缘骨密质增厚。结论??成牙骨质细胞瘤在临床及影像表现上有其较明显特征性，临床医生应充分认识这一病变以免误诊。
