The MRI sequences demonstrate an intradural extramedullary dumbbell mass at the C4-C5 level, extending through an enlarged left C4-C5 exit foramen. It is isointense to the spinal cord on T1WI, inhomogeneous high signal on T2WI with homogeneous enhancement following IV contrast. The adjacent segment of the spinal cord is compressed and displaced to the right with no signs of compressive myelopathy.
