摘要
目的:探讨颌骨促结缔组织增生性纤维瘤(DFB)的影像学特征和鉴别诊断。方法:根据1例DFB病例进行影像学分析及文献复习。结果:DFB在X线上表现为溶骨性骨质破坏,无骨膜反应;CT上见骨小梁吸收破坏,为软组织密度肿物取代,增强检查可见强化;MRI上表现为正常骨质信号消失,软组织信号出现,T1WI为均匀等信号,T2WI为不均匀高信号。结论:DFB是罕见的起源于结缔组织的原发骨肿瘤,是具有侵袭性生长特点的良性肿瘤,治疗上宜采取术区扩大切除防止复发。因此,术前从影像学上鉴别DFB对于术式选取以及治疗效果至关重要。
Objective:To investigate the imaging features and differentiated diagnosis of desmoplastic fibroma of jaw bones. Method:Imaging features of 1 case of DFB were retrospectively analyzed ,and the relevant literatures was reviewed. Result:The main appearance of DFB on X-ray radiographys were osteolytic bony destruction ,without periosteal reaction;On CT scan,the bone trabecular was absorbed and damaged,being replaced by soft tissue,and the lesion was found enhanced on enhancement CT scan;the normal signal of bones disappeared on MRI,while soft tissue signals turned up,with homogeneous hypointensity on T1WI,non-homogenous hyperintensity on T2WI. Conclusion:DFB is a rare primary bone tumor originated from the connective tissue, it is also an benign tumor with aggressive growth characteristics. Expanded area surgery should be take to prevent recurrence. Therefore,the prior identification of DFB in imageology is vital for the selection of surgery and treatment effect.
