长骨嗜酸性肉芽肿DR、CT和MRI表现探讨

Study on the Expression of Long Bone Eosinophilic Granuloma DR,CT and MRI

目的:探讨分析长骨嗜酸性肉芽肿的DR、CT和MRI影像学表现及其诊断价值。方法:选取自2012年11月~2017年1月本院收治并确诊为长骨嗜酸性肉芽肿的16例患者的影像学及病历资料进行回顾性分析,病灶均为单发,其中,15例患者行DR检查、11例行CT检查、12例行MRI检查,分析其在DR、CT及MRI上的表现。结果:影像学特点为:病灶处溶骨性破坏,多位于干骺端至骨干,破坏随着骨髓腔呈纵向延伸,病变周围骨质硬化,多伴有层状骨膜反应,骨皮质变薄并可见破坏、可伴软组织肿块。结论:DR、CT及MRI在诊断长骨嗜酸性肉芽肿上各有其优缺点,三者结合多能明确定性、诊断,但部分急性病变影像表现与恶性肿瘤相似,需多加鉴别。

Objective： to explore the diagnostic value of DR, CT and MRI in the analysis of long bone eosinophilic granuloma. Methods： Selection November 2012 - January 2017, our hospital and diagnosed with long bone eosinophilic granuloma of imaging and medical records of 16 patients were retrospectively analyzed, the lesions are single, among them, 15 cases of patients with DR check routine MRI routine CT examination, 11, 12, to analyze its performance on the DR, CT and MRI. Results： imaging characteristics as follows： at the bony destruction, mostly on stem epiphyseal end to the backbone, longitudinally extended as the marrow cavity, around the lesions, bone sclerosis with layered periosteal reaction, thinning of the bone cortex and visible damage, can be associated with soft tissue mass. Conclusion： DR, CT and MRI in the diagnosis of long bone eosinophilic granuloma each have their advantages and disadvantages, the combination can clear qualitative, diagnosis, but some acute lesions imaging performance similar to malignant tumor, need to identify more.
