There is a significant distortion of the thecal sac in the mid thoracic column, at T6 to T8 levels. The cord is markedly distorted in the region and pushed back posteriorly. The cord appears to be tagged posteriorly at several points, and the source of this is not appreciated, appearances are those of posterior adhesions with the dorsal aspect of the sac. Altered CSF flow mechanics within the region contributes to dephasing loss of signal within the CSF. The vertebral bodies, intervertebral discs, and intervertebral foramina are unremarkable.
