%X 【】目的探讨颈椎后纵韧带骨化症(OPLL)的CT表现及其诊断价值。方法回顾性分析2004年11月-2009年10月收治的6480例颈椎患者的CT图像资料，观察后纵韧带骨化块的形态、位置及与椎管的关系，计算椎管狭窄率。结果6480例颈椎CT图像中，37例发现OPLL，占0.57%（37/6480）。颈椎后纵韧带骨化块表现为点状、条状、线状、平板状、山丘状、蕈伞状及花边状，呈现局限型、节段型、连续型、混合型特点。C4、C5及C6为颈椎后纵韧带骨化常见位置。骨化块平均厚度为4.12mm，骨化块致椎管矢状径狭窄率为10.20%～49.18%，多位于椎管前方中间位置。椎管狭窄率>34.10%，临床症状明显。结论CT检查能较好地显示颈椎后纵韧带骨化块的特征及椎管的狭窄程度，是临床医生选择手术方案和术后评估预后的一种较好方法。？【Abstract】ObjectiveTostudytheCTmanifestationsofossificationofposteriorlongitudinalligament(OPLL)andtoevaluatediagnosticvalue.MethodsRetrospectiveanalysiswasmadeonthecervicalspineCTimagesof6480cases,and37casesofOPLLwerefound.Theshape,locationoftheossificationpiecesandthesagitaldiameterofcervicalspinalcanalandthestenoticratewereobservedandmeasured.ResultsTheossifiedpiecesweremanifestedasdots,belts,lines,boards,mounds,mushroomsandflowermarginsinshape.Theywerecontinuous,segmental,solitaryormixed.OPLLusuallywasfoundatC4,C5andC6.Theaveragethicknessoftheossifiedpieceswas4.12mm.Thespinalstenoticraterangedfrom10.20%to49.18%duetoOPLL.Theossifiedpieceswereoftenfoundatthemiddleofthebackedgeofcervicalvertebraebodies.Therewereobvioussymptomswhenthestenoticrateofsagitaldiameterofcervicalspinalcanalwasover34.10%.ConclusionCTisanoptimalmodalityfordiagnosisofOPLLofcervicalspineandcervicalspinalstenosis,andmayhelptheclinicianstoselectorvaluateoperationproject.
