case_images: (a) Initial sagittal T2-weighted image showing the abnormal high intensity (yellow arrow) of cervical cord compressed by retro-odontoid pseudotumor, (b) initial axial T2-weighted image showing markedly compressed cervical cord yellow arrow by retroodontoid pseudotumor.

case_images: The cervical MR showed a low-intensity mass behind the odontoid process that compressed the cervical spinal cord and resulted in a high intrinsic cord signal [Figure 1].
case_images: Two years later, T2-weighted images after botulinum muscle injection showing reduced retro-odontoid pseudotumor and resolution of cervical cord compression. (a) sagittal, (b) axial.

case_images: Two years later, the MR confirmed the reduction in size of the ROP mass that correlated with the regression of cord compression and the high intrinsic cord signal [Figure 2].
