Abstract

Objective To improve the knowledge of lumbar posterior marginal intraosseous cartilaginous node (LPMN)and discuss its related etiological factors.MethodsThe CT manifestation of 42 LPMN cases were analysed. Result Three major CTfindings were : ①a defect in the posterior superior margin ofthe affected vertebral body, with sclerotic margin.②posterior tothe defect,a bonyfragment was seen protrudingintothe spinal canal;③compression of the dural sac and nerve root. Conclusion The CT scanning has definite diagnositic value for the lumbar posterior marginal intraosseous cartilaginous node.
