Magnetic resonance imaging confirmation of resolution of periodontoid @entity2070 formation following XXXX posterior transarticular screw fixation.

@entity1 @entity174 @entity602 @entity2070 @entity51 @entity1745 @entity6350
@entity174 are considered unstable spinal lesions. Chronic instability in this region leads to the development of an inflammatory @entity2070 , which can progress resulting in @entity1745 radiographically and a @entity602 clinically. In this report we document three cases of reversal of @entity2070 after @entity6350 transarticular screw fixation of an unstable odontoid @entity174 . Three @entity1 were identified with @entity174 and @entity1745 due to periodontoid @entity2070 formation. All @entity1 presented with a progressive @entity602 . All @entity1 underwent preoperative and postoperative magnetic resonance imaging (MRI) of the craniovertebral junction. @entity6350 transarticular screw fixation was performed for stabilization of @entity6350 . Postoperatively there were no complications. Postoperative MRI at 6 months demonstrated resolution of the ventral @entity2070 . Moreover, all @entity1 exhibited improvement of preoperative @entity51 . MRI is the imaging technique of choice for diagnosis and follow-up of @entity1 with @entity174 . @entity6350 transarticular screw fixation provides a viable method for spinal stabilization in this region. In addition, stabilization can result in resolution of inflammatory @entity2070 formation secondary to instability of the @entity6350 articulation.
