“…9 The purpose of this study was: (1) to identify whether certain patterns of imaging abnormality on MR are associated with the delayed development of spinal cord cyst; and (2) to attempt to correlate changes in the neurological status following acute spinal trauma with the change in MR appearances of the spinal cord.…”

In a series of 15 patients who underwent early and follow up magnetic resonance imaging following spinal cord injury, those with focal spinal cord abnormalities such as cord contusion or haematoma had worse neurological outcomes, and most developed spinal cord cysts, showing as well-defined areas of CSF intensity within the cord on Tl weighted images. Patients with cord oedema initially, had better outcomes, with the development of residual areas of myelomalacia. These observations suggest that patients with focal initial spinal cord abnormalities may have an increased risk of developing posttraumatic spinal cord cysts, which may be associated with the development of delayed neurological deterioration.

Background/Objective: An assessment of neurological improvement after surgical intervention in the setting of traumatic thoracic spinal cord injury (SCI).Methods: A retrospective evaluation of a nonconsecutive cohort of patients with a thoracic SCI from T2 to T11. The analysis included a total of 12 eligible patients. The neurologic and functional outcomes were recorded from the acute hospital admission to the most recent follow-up. Data included patient age, level of injury, neurologic examination according to the Frankel grading system, the performance of surgery, and the mechanism of the time-related SCI decompression.Results: All patients had a complete thoracic SCI. The median interval from injury to surgery was 11 days (range, 1-36 days). Decompression, bone fusion, and instrumentation were the most common surgical procedures performed. The median length of follow-up was 18 months after surgery (range, 9-132 months). Motor functional improvement was seen in 1 patient (Frankel A to C).Conclusion: Surgical decompression and fusion imparts no apparent benefit in terms of neurologic improvement (spinal cord) in the setting of a complete traumatic thoracic SCI. To better define the role of surgical decompression and stabilization in the setting of a complete SCI, randomized, controlled, prospective studies are necessary.J Spinal Cord Med. 2005;28:415-420

The evolution of intramedullary lesions following an acute spinal cord injury was monitored with sequential magnetic resonance (MR) imaging. Seven patients who had sustained cervical spinal cord injuries were followed up from the acute to the chronic phase of the cord injury. MR images were evaluated not only qualitatively but also quantitatively. All intramedullary lesions were quantita tively analysed by T2 values. In the qualitative analysis, the regions with hyperintensity on T2-weighted images and isointensity on T1-weighted images were consistent with the region of simple oedema or gliosis. The former gradually disappeared after the acute phase, whereas the latter remained until the chronic phase. The regions with hyperintensity on T2-weighted images and hypointensity on Tl-weighted images may represent cysts filled with necrotic tissue or clear fluid, or necrosis. The evolution of these lesions was also able to be monitored quantitatively by T2 values.
