Case #31


Findings

  • Moderate disc dessication and height loss at L5-S1 with a right paracentral and subarticular disc protrusion effacing the subarticular zone and contacting and displacing the descending right S1 nerve roots. Herniated disc material also contacts, but does not displace the descending right S2 nerve roots
  • Facet hypertrophy contributes to mild bilateral neural foraminal stenosis at L5-S1
  • Minimal left eccentric broad-based disc bulge at L4-L5 and associated dorsal osteophytic ridging contribute to mild crowding of the left subarticular zone
  • No significant degenerative changes above the level of L4-L5 in the lumbar spine
  • Central T2 hyperintense structure in the spinal cord extending from the level of T11-T12 through the conus measuring up to 2 mm in transverse diameter without surrounding cord signal abnormality or significant expansion of the cord or conus
  • Conus terminates at the level of L2


Diagnosis

  • Terminal ventricle

Sample Report

Moderate disc dessication and height loss at L5-S1 with a right paracentral and subarticular disc protrusion effacing the subarticular zone and contacting and displacing the descending right S1 nerve roots. Herniated disc material also contacts, but does not displace the descending right S2 nerve roots. Facet hypertrophy contributes to mild bilateral neural foraminal stenosis at L5-S1.

Minimal left eccentric broad-based disc bulge at L4-L5 and associated dorsal osteophytic ridging contribute to mild crowding of the left subarticular zone.

Central T2 hyperintense structure in the spinal cord extending from the level of T11-T12 through the conus measuring up to 2 mm in transverse diameter without surrounding cord signal abnormality or significant expansion of the cord or conus, favored to represent a terminal ventricle rather than a small syrinx.
