目的：研究颌骨成釉细胞瘤的 X 线和 CT 影像学特点。方法回顾性分析20例经手术病理证实的颌骨成釉细胞瘤的 X线平片(9例)和 CT(20例)表现。观察病变的部位、大小、形态、囊内容物的密度及周围骨质改变等。结果19例位于下颌骨,其中10例位于磨牙升支区,4例累及下颌骨体整半,2例累及下颌骨体整半及对侧颏部,1例累及整个下颌骨体,2例位于下颌骨前牙区及颏部；1例位于上颌骨磨牙区。3例为单房型,17例为多房型。20例周围骨质均呈膨胀性改变,15例向唇颊侧膨胀明显,3例向舌侧膨胀明显,2例均匀性膨胀。19例造成周围骨皮质中断。结论颌骨成釉细胞瘤有一定的特征性影像学表现,对其准确的把握有利于提高术前诊断的正确率。

Objective The purpose of the study was to characterize the X-ray and CT findings of ameloblastomas of the jaw.Meth-ods X-ray (n=9)and CT (n=20)findings of 20 patients with pathologically proven ameloblastomas of the jaw were obtained.Image features included location,size,shape,density of the lesion,and changes of adjacent bone were assessed.Results 1 9 cases were located in the mandible,including 10 cases in the molar-ramus region,four cases in the whole half of the mandible body,two cases in the whole half of the mandible body and the opposide mantum,one case in the whole mandible body,two cases in the anterior teeth region and mantum.One case was located in the molar region of the maxilla.Three cases were uniocular and 17 cases were multiocular in shape.All lesions caused expansile changes in the adjacent bone,including expanding towards the lip and bucca(n=15),the lingua(n=3),and expanding uniformly(n=2).The interruptions of the surrounding bone cortex were demonstrated in 1 9 cases.Conclusion There are some characteristic imaging find-ings for ameloblastomas of the jaw.Correct preoperation dignosis can be made on the basis of imaging findings.
