【摘要】目的探讨非骨化性纤维瘤的临床及x线表现以提高诊断水平。方法所有病例均摄有x线平片,分析经病理证实的12例非骨化性纤维瘤。结果临床症状轻,好发于下肢长骨干骺端或骨干,股骨6例,胫骨4例,下颌骨及肋骨各1例;皮质型10例表现为皮质内或紧贴皮质下的单层或多层透亮区,病变向骨内发展进入髓腔,周围有致密硬化带环绕,以髓腔侧明显;髓质型2例,病灶在骨内中央发展,显示为单房或多房透亮区,边缘有硬化,骨皮质菲薄,轻微向周围膨隆。结论x线为最基本检查方法,典型病例x线平片结合临床症状即可明确诊断。

骨的非骨化性纤维瘤是一种比较少见的原发性良性肿瘤,国内多为零星报道,笔者收集我院自1984~2004年近20年来经病理手术证实的非骨化性纤维瘤(non-ossifyingfibroma,nof)进行回顾性分析。以提高对nof的认识和诊断水平。
