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
