Baastrup病的影像学表现

Imaging Findings of Baastrup Disease

目的探讨Baastrup病的影像学表现及其临床意义。方法收集分析我院2011年11月至2015年2月间250例Baastrup病患者的影像学资料,全部行腰椎DR检查,其中54例加做腰椎MRI检查,19例加做腰椎螺旋CT检查,共有12例同时进行三种检查。结果 Baastrup病患者腰椎棘突相互靠近、撞击致相对缘骨质增生、硬化,棘突呈杵状增粗,相对面变平,甚至形成假关节,关节面下可见囊状低密度区;MRI T2WI序列可表现为棘突间高信号改变或无明显异常信号改变。患者有程度不等腰背部疼痛病史,受累棘突有固定压痛。多发生于50岁以上老人,多数伴有腰椎退行性改变。结论 Baastrup影像学表现具有特征性,正确认识此征象,有助于解释下腰部疼痛并指导临床开展治疗。

Objective To analyze the imaging findings and clinical vale of Basstrup diseas. Methods 250 cases of imaging date of Baastrup diseas in our hospital from November 2011 to February 2015 were analyzed retrospectively, All of them underwent lumbar Digital radiography （DR） examination, including 54 cases with Magnetic resonance imaging （MRI） examination, 19 cases with lumbar spiral Computer tomography （CT） examination, a total of 12 patients also underwent both of three types examinations. Results Baastrup diseas develops when there is close approximation and impingement of one spinous process on another, which leads to reactive sclerosis, enlargement, flattening, even the form of pseudarthrosis.Conclusion MRI shows high signal between the involved spinous processes or normal.All patients with a history of lumbar pain and tenderness involved spinous processes.
