摘要
作者报告１０例有症状的胸椎黄韧带骨化的ＣＴ检查结果。特征性ＣＴ表现有：（１）两侧椎板前缘“Ｖ”形骨化块突入椎管，（２）小关节囊和椎板间也可受累，沿椎板前缘形成广泛的骨化块，（３）椎板硬化增厚，（４）椎弓根短缩，（５）椎管狭窄。讨论了ＣＴ及其他影像学对黄韧带骨化的诊断价值。作者认为ＣＴ和／或ＣＴＭ是目前诊断本病的较佳方法，对手术治疗方案的制定也非常有用。
AbstractA CT study on 10 cases with symptomaticossification of the ligamentum flavun(OLF) in thethoracic spine was reported.The characteristic CTfeatures were:(1) v-shaped ossified excrescence on theanterior rnargin of the larnina,(2) ossificationinvolving the joint capsules and interlaminar portions,fOrming an extensive mass in the posterior portion ofthe spinal canal,(3) thickening of the laminar archand facet joints,(4)shortening of the pedicles,(5)narrowing of the spinal canal.The value of CT andother imaging modalities in the demonstration of OLFwere briefly discussed.The author believes CT and /or CT myelography should be the best method ofchoice for the diagnosis of this entity,and is veryuseful in planning the surgical approach.
