DEGENERATION OF THE POSTERIOR COLUMNS OF THE SPINAL-CORD - POSTMORTEM MRI AND HISTOPATHOLOGY

Postmortem MR images of two cases of posterior column degeneration were correlated with histopathological findings. The abnormal MR findings were volume loss and high signal intensity ot the posterior columns associated with mild deformity of the dorsal surface ot the spinal cord, corresponding to tract degeneration on histopathological examination. These results strongly suggest that further development of MR technique will permit in vivo detection of posterior column degeneration.
