目的 分析腰椎前椎缘骨的影像 学表现特征。方法 回顾性分析丰县人民 医院影像科2013年5月-2015年6月诊断的 12例腰椎前椎缘骨影像学表现。8例由CT 诊断，2例由MRI诊断，2例由CT与MRI共同 诊断。结果 病变位于腰椎椎体前上缘11 例，前下缘1例，其中位于L4椎体6例，L5 椎体4例，L3椎体1例，同时位于L4及L5椎 体1例。影像学表现为椎体前缘骨质局部 缺如，缺损区内见软组织密度或信号灶， 病灶超出相邻椎体前缘连线，椎间盘前纤 维环前凸，前纵韧带明显受压前凸。结论 腰椎前椎缘骨主要发生于L4、L5椎体前上 缘，影像学表现具有特征性。

Objective To analyze the imaging features of lumbar anterior limbus vertebra. Methods From May2013 to June 2015, in the Hospital of Feng-xian county, the clinic and MRI data of 12 patients diagnosed with lumbar anterior limbus vertebra were retrospective analyzed. 8 cases were diagnosed by CT, 2 cases diagnosed by MRI, 2 cases by CT and MRI. Results 11 cases located in the front upper margin, 1 case located in the front lower margin. Of them, 6 cases located in L4, 4 cases in L5, 1 case in L3, Both L4 and L5 vertebral bodies involved in 1 case.On imaging, local bone defect in the anterior margin of the involved vertebral body, the defect area with soft tissue density or signal lesions, the anterior margin of involved front-plate exceeded normal vertebral margin, margin, the anterior fibrous of disc protruded anteriorly and anterior longitudinal ligament were pressed. Conclusion Lumbar anterior limbus vertebra mostly betide in the front upper margin of L4 and L5. The imaging features of lumbar anterior limbus vertebra are characteristic.
