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
