骨纤维异常增殖症的影像诊断

Radiological Diagnosis of Fibrous Dysplasia of Bone

目的:分析骨纤维异常增殖症的临床特征并比较X线、CT、MRI的影像学表现,探讨X线、CT、MRI对骨纤维异常增殖症的诊断价值。材料与方法:收集45例由手术病理证实的骨纤维异常增殖症的X线、CT和MRI表现特点。结果:X线表现较复杂,CT表现主要为磨玻璃样改变、囊状低密度影和斑块样硬化,无明显骨膜反应存在。由于在病理上组织成份的不同,MRI所呈现的信号特点依赖于骨小梁、细胞成份及胶原纤维的多少。结论:X线仍是诊断骨纤维异常增殖症的良好方法,若位于颌面部或颅底时可采用CT检查,明确骨纤维异常增殖症骨受累程度、范围和细节等。MRI对判断周围组织变化有帮助。

Purpose： Goal to analysis characteristic of fibrous dysplasia of bone and compares X, CT, the MRI image study performance, discusses X, CT, MRI to fibrous dysplasia of bone diagnosis value. Materials and Methods： Collects 45 cases of fibrous dysplasia of hone which confirms by the surgery pathology X, CT, and MRI performance characteristic. Results： X- ray performance is more complex,CT performance mainly for rough hyalo- like change, pouch shape low deity shade and mottling type hardening, not obvious periusteal reaction existence. Because organizes the ingredient in the pathology the difference, MRI presents does the signal characteristic rely on bone trabecula, how many the cell ingredient and enlhgenous fibers. Conclusion： X- ray still wass good method in diagnoses of fibrous dysplasia of bone, if located the jaw face or when the skull bottom might use the CT inspection, made clear the dysplasia of bone exhausts oneself the degree, the scope and the detail and so on. MRI to judges periphery organizes the change to have the help.
