目的分析非骨化性纤维瘤(NOF)的X线及CT表现,并结合病理特征,以提高NOF的诊断与鉴别诊断水平.方法回顾性分析28例经手术病理证实的NOF患者X线及CT表现.结果临床症状轻微,好发于长管状骨的干骺端或骨干,病变发生于胫骨18例,股骨9例,肱骨1例,皮质型19例,表现为皮质内或紧贴皮质下的单房或多房透亮区,周围有致密的硬化带环绕；髓质型9例,病灶在骨内呈中央性发展,显示单房或多房透亮区,边缘硬化,骨皮质变薄,轻度向周围膨隆.结论 NOF的影像学表现具有一定的特征性,X线及CT是诊断NOF的非常有用的方法,多层螺旋CT的薄层扫描及多平面重建能更清晰地显示NOF的影像特征.

Objective To improve the accuracy of diagnosis and differential diagnosis of nonossifying fibroma (NOF) by comparing with the image features of X-ray and CT and pathological characteristics,Methods The images of X-ray and CT of 28 patients underwent surgery and pathological confirmed NOF were studied retrospectively.Results NOF often occurred in the metaphysis of long bone or backbone with mild clinical symptoms.Eighteen lesions occurred in tibia,9 in femur and 1 in humerus.In 19 cortical cases,there was a single room or multiple rooms translucent zone in cortex or subcortex with dense surrounding.In 9 medullary cases,lesions as a single room or multiple rooms ranslucent zone with dense surrounding developed in the central area of the bone with thinning corex slightly bulg ed to periphery.Conclusion The images of NOF have some characteristic.X-ray and CT are very useful tools in diagnosis of NOF.Thin layer scanning and multiplanar reconstruction of multi-layers spiral CT can more clearly show the imaging features of NOF.
