Syringomyelia is defined as a fluid-filled cavity within the Spinal cord, which is observed particularly at the cervical and thoracic levels and, less commonly, in the lumbar region. In up to 70 % of cases, syringomyelia is associated with an Arnold–Chiari type I malformation and in approximately 10 % of cases with Basilar invagination; however, it may also be associated with tumors or occur post-traumatically or post-infectiously[^1].
Symptoms
The clinical presentation of syringomyelia can be highly variable. The symptoms usually progress over months or years, with an initially rapid deterioration that slows over time[^1]. Symptoms may manifest, for example, as pain, a feeling of weakness, atrophy, and loss of temperature and pain sensation[^1].
Imaging
The gold standard for imaging syringomyelia is MRI.
