Kümmell 病的影像学诊断分析

Diagnostic analysis of the radiologic characteristics in osteoporotic Kümmell's disease

目的 ：探讨骨质疏松性Kümmell病的影像学特征对其诊断价值。方法 ：2010年5月至2014年5月共收治经病理证实的Kümmell病患者16例,男4例,女12例;年龄67~83岁,平均73.4岁;腰背部疼痛病史2个月~3年,平均4.7个月。回顾性分析所有病椎X线片,CT横断位、矢状位和冠状位重建与MRI矢状位T1WI、T2WI及STIR影像学资料。结果：正侧位X线片病椎可见线形透亮线样＂椎体裂缝征＂,CT可见椎体内伴有气体和（或）液体的空壳样改变,MRI提示椎体出现边界完整的液体信号区域。结论：骨质疏松性Kümmell病影像学表现具有一定特异性,结合临床发病特点,为早期明确诊断提供依据。

Objective：To explore the diagnostic value of the radiologic characteristics of osteoporotic Kümmell′s disease.Methods：Total 16 patients with pathologically confirmed osteoporotic Kümmell′ s diseases were reviewed from May 2010 to May 2012,including 4 males and 12 females with the mean age of 73.4 years（ranged,67 to 83 years old）. Radiologic imagings of all patients,including X-ray,CT and MRI,were analyzed retrospectively. Results：Intravertebral linear clefts could be seen on the AP and lateral X-ray films of vertebrae. Sagittal and axial CT scans demonstrated the vacuum cleft phenomenon with liquid and air was identified within the vertebral body. Sagittal MRI showed the callapsed vertebral segment and the area of fluid signal with clear and intact border within the vertebral body. The fluid signal was low on T1 weighted images and high on T2 weighted images and stir images,which was corresponding to an intravertebral vacuum cleft. Conclusion：The radiologic characteristics of Kümmell＇s diseases can provide valuable evidences for the early diagnosis.
