Clinical question: Evaluate thoracic syrinx-preoperative planning for tube insertion. Signs and symptoms: Chest and back pain. Nonenhanced thoracic MRI:Examination is degraded due to motion artifact which makes precise assessment of subtle findings not possible however studies remains diagnostic.There is revisualization of an expansile syrinx of thoracic cord extending from approximately T3 level inferiorly to T12 no without change in its extent and without convincing evidence of any appreciable change in its size/diameter. Similar to prior exam a thin linear T2 hyperintensity representing a drain is noted entering the spinal canal posteriorly from T9 -- T10 disk level and terminating superiorly at lower T8 level. The drain does not appear to remain in a straight axis and suspected of having kink or tortuosity within the cord similar to prior study.Small previously noted epidural collection at the site of surgery/site of insertion of drain demonstrate complete interval resolution. Minimal postoperative fluid collection in the musculature of mid back is also no longer detected and presumed resolved.
1.No evidence of appreciable interval change in the extent or laminar of syrinx of thoracic cord since prior exam.2.Revisualization of a drain entering the spinal canal at T9 -- T10 disk level and with the tip within the cord.3.Irregular coarse of the drain within the cord remains similar to prior exam.4.Interval resolution of postoperative small epidural at T9 -- T10 as well as resolution of post operative fluid collection within the musculature of mid back.
