愈合期非骨化性纤维瘤的影像学表现

目的探讨愈合期非骨化性纤维瘤影像学诊断及其临床意义。方法对10例经随访观察和手术病理(2例)确认的愈合期或愈合型非骨化性纤维瘤的影像学表现进行分析。所有病例经X线摄影,4例经CT检查,1例行MRI。结果10例均发生在下肢长骨,胫骨8例,股骨2例。5例表现为均匀的硬化灶,5例在硬化灶中心存有透光区。5例分别经随访观察1~4年无变化。结论非骨化性纤维瘤可于青春期演变为硬化性的静止性病变而达到自愈。愈合期或愈合型非骨化性纤维瘤不需要手术治疗。

The Appearances of Imaging in Healed form Non-ossifying Fibroma

Objective To investigate the imaging appearances of non-ossifying fibromas in healing stage and its clinical value.Methods The imaging features of non-ossifying fibroma in healing stage in 10 cases followed-up clinically(2 cases of them were verified by pathology after operation) were analyzed. All of the cases were examined by radiography,4 cases were examined by CT, 1 case underwent MRI. Results All of the cases were located in long bone of lower extremity. 8 cases were in tibia,2 cases were in femur. 5 cases were shown as homogeneous sclerosis,lucent areas were presented in sclerotic foci in 5 cases. 5 cases were unchangeable after followed-up 1 to 4 years .Conclusion The non-ossifying fibroma is being sclerotic stabilized foci after puberty , no operation is necessary for the healed form non-ossifying fibroma.
