Study Notes
Pathophysiology of Post-Traumatic Syringomyelia
- The exact pathophysiology of post-traumatic syringomyelia is not fully understood
- Factors contributing to syrinx formation include: mechanical compression of the spinal cord, inflammation, hematoma, release of intracellular lysosomal enzymes, ischemia, and obstruction of arterial and venous supply
Clinical Presentation of Syringomyelia
- Classic presentation: cape-like bilateral distribution of pain and temperature loss in the shoulders, arms, and hands due to destruction of spinothalamic tracts
- The dorso-lateral column of the spinal cord is often spared, leaving fine touch, vibration, and proprioception intact
- Atypical presentations can occur due to variability in syrinx location within the spinal cord
Case Report: Unusual Presentation of Syringomyelia
- Patient presented with loss of pain, temperature, and fine touch in the left upper limb, with severe dysesthetic pain in the neck, shoulder, and upper back
- Unusual non-dissociated type of sensory loss explained by expansion of syrinx affecting posterior columns of the spinal cord or compression of dorso-lateral region
- Absence of pyramidal signs due to sparing of corticospinal tracts
Surgical Management of Post-Traumatic Syringomyelia
- Laminectomy with direct drainage of the syrinx can provide temporary relief from dysesthetic pain
- Shunting procedures (syringo-peritoneal, syringo-pleural, or syringo-subarachnoid) may be considered, but their superiority is controversial
- Surgery can enhance quality of life and reduce healthcare costs, even with modest improvement or temporary halting of neurological deterioration
Explore the factors believed to precede the formation of syrinx within the spinal cord in post-traumatic syringomyelia. Learn about mechanical compression, inflammation, hematoma, lysosomal enzymes, ischemia, and vascular supply obstruction contributing to syrinx expansion.
