Abstract:
Objective To investigate MRI characteristics of subacute combined degeneration(SCD)with secondary spinal canal stenosis.Methods The clinical and MRI imaging data of 56 patients with SCD were collected to analyze the performance characteristics between spinal cord lesions and spinal canal stenosis,which depended on the synergism of lumbar disc bluge or herniation,degenerative thickening of the ligament flavum and posterior longitudinal ligament.Results Among 56 SCD cases underwent MRI scan,45 cases were combined with spinal cord lesions which showed typical signs of SCD.37 patients were secondary spinal canal stenosis with typical signs,but 2 showed no typical signs.8 patients were no secondary spinal canal stenosis and showed typical.9 cases showed neither spinal cord lesions nor secondary spinal canal stenosis.There was significant difference (P <0.05)between relative secondary spinal canal stenosis and spinal anomaly signal.The course of 1 5 cases were shortened after treated by physical in 37 cases of SCD with secondary spinal canal. Conclusion The secondary spinal canal stenosis can cause microcirculation dysfunction of the spinal cord,which is a key factor contributing to the imaging manifestation.
