History of multiple sclerosis: pain and numbness. There appears to be faint T2 hyperintensity in the mid thoracic spinal cord, with perhaps mild volume loss. 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 or neural foraminal stenosis. However, there is an unchanged T2 hyperintense lesion in the right S2-3 neural foramen that measures 15 mm in width. There is also a punctate perineural cyst in the incompletely imaged right C6-7 neural foramen. The paravertebral soft tissues are unremarkable.
1. Apparent faint T2 hyperintensity in the mid thoracic spinal cord, with perhaps mild volume loss may represent a chronic demyelinating lesion. 2. An unchanged T2 hyperintense lesion in the right S2-3 neural foramen is incompletely characterized without intravenous contrast, but likely represents a perineural cyst.
