摘要
目的探讨青少年和成人脊柱嗜酸性肉芽肿(EG)在影像学表现的差异。方法分析21例手术后病理证实的脊柱EG,比较青少年和成人脊柱EG在X线平片、CT扫描和MRI影像上的差异。结果青少年脊柱EG具有典型X线片表现—扁平椎,成人不具有类似典型的表现;CT扫描青少年和成人类似,均表现为患椎椎体溶骨性破坏;MRI青少年和成人患椎T1加权像均表现为等信号,而T2加权像,青少年呈现等信号或中等信号增高,且相邻椎间盘呈现高信号改变。成人呈现高信号改变,患椎相邻椎间盘呈现高信号改变或中等信号。结论脊柱EG青少年X线平片具有典型改变,成人则无。CT、MRI可以显示病变侵犯椎体的程度和范围及脊髓损伤程度,从而决定治疗方式。
Objective To study of difference of image of eosinophilic granuloma of spine in adolescent and adult, Methods 21 cases of eosinophilic granuloma （EG） of spine, which were comfirmed by post-operation pathology, were recruited and compared the image difference of between adolescent and adults in X-ray film, CT, and MRI. Resuits X-ray film of adolescent with EG revealed a typical vertebral plana, but the adults revealed different severity of vertebral collapse, The linage of CT scan between adolescent and adults were similar,all revealed lytic lesion in vertebral, The T1-weighted MRI image between the adolescent and adult are similar.and revealed isointensity signal as normal vertebral. The T2-weighted MRI image revealed the iso- or moderately increased signal in adolescent,and the height increased signal in adults, the intervertebral discs closed to the lesion vertebra revealed height increased signal in adolescent, and height or moderately increased signal in adults. Conclusions The typical X-ray film characteristics can be found in adolescent, but not in aduhs. CT scan and MRI can reveal the severity and region of lytical lesion in vertebra and the severity of spine injury,and determine the strategy of the treatment of eosinophilic granuloma of the spine.
