  • Syringomyelia is a disorder of CSF and therefore understanding the pathogenesis of this enigmatic disorder is dependent on understanding CSF flow dynamics, biochemistry and factors that influence its absorption and The majority of CSF is produced by the four choroid plexuses (one in each ventricle of the brain), which circulates through the ventricular system and the subarachnoid spaces of the brain and spinal cord (9, 10).

  • Syringomyelia is a condition characterised by fluid filed cavities (syrinxes or syringes) within the central spinal cord and the resulting damage produces clinical signs of pain and neurological deficits. (marysfamilymedicine.org)

  • The retained medullary cord (RMC), caudal lipoma, and terminal myelocystocele (TMCC) are thought to originate from the failed regression spectrum during the secondary neurulation, and the central histopathological feature is the predominant presence of a central canal-like ependyma-lined lumen (CC-LELL) with surrounding neuroglial tissues (NGT), as a remnant of the medullary cord. (surgicalneurologyint.com)

  • 2) The rise of distal syringomyelia isn't only linked to the kind of the spinal lipoma, but also to the difficulty to obtain the untethering and a smooth cerebrospinal fluid flow between the subarachnoidal space and the ependymal canal. (nih.gov)
  • The distal or terminal portion of the spinal cord is referred to as the conus medullaris. (medscape.com)
