Chiari malformation, thoracic lesion, syrinx, follow up. There is slight dilatation of the central canal in the thoracic spinal cord at T4 and T9 to T11, measuring up to 1 mm in diameter. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The paravertebral soft tissues are unremarkable. The cerebellar tonsils appear to be mildly low-lying on the localizer images.
