目的分析非骨化性纤维瘤的X线、CT表现,以提高非骨化性纤维瘤的诊断水平。方法分析9例经手术病理证实的非骨化性纤维瘤患者的临床表现及X线、CT表现。结果股骨下端5例,胫骨上端3例,腓骨下端1例;①偏心型(皮质型)8例,其中表现为卵圆形分叶状透亮区6例,多房性透亮区2例,皮质均膨胀变薄,边缘锐利;有窄细硬化边7例;无硬化便1例。②中心型(髓质型)1例,表现为细管状骨髓腔内多囊状透亮区,其中可见骨性分隔,边缘锐利,有菲薄的骨壳硬化边。结论X线为非骨化性纤维瘤的首选检查方法,CT可作为补充,X线平片结合CT表现及临床资料可提高非骨化性纤维瘤的诊断准确率。
Objective To analyze the X-ray and CT findings of non-ossifying fibroma in order to improve the diagnosis of non-ossifying fibroma. Methods Nine cases of non - ossifying fibroma confirmed by surgery and pathology were analyzed with X - ray and CT findings. Results There were 5 cases of inferior femur, 3 cases of upper tibia and 1 case of lower fibula. ① Eccentric (cortical) 8 cases showed oval lobular translucent region in 6 cases, multilocular translucent region in 2 cases, cortex Expansion thinning, sharp edges; narrow fine sclerosis in 7 cases; no sclerosis in 1 case. ② central type (medullary type) in 1 case, showing a thin tubular marrow cavity multi-cystic translucent area, which can be seen bony separation, sharp edges, there are thin side of the shell hardening. Conclusion X-ray is the first choice for non-ossifying fibroma, CT can be used as a supplement, X-ray combined with CT findings and clinical data can improve the diagnostic accuracy of non-ossifying fibroma.
