Figure 2: T2, T1 and post contrast images of sagittal and axial sections. Fig A. Sagittal T2-weighted MR image shows abnormally increased signal intensity (arrows) along the posterior columns of the spinal cord extending from C2 through C6 level. Fig d. Axial T2-weighted MR image shows abnormal signal intensity (arrows) along posterior columns showing inverted V sign. It appears isointense on T1-weighted MR images (figures b & e). No post contrast enhancement noted (figures c & f)
