Abstract:
Transdural herniation of the spinal cord is thought to be previously extremely rare and very often misdiagnosed. Possible reasons may be iatrogenic and traumatic or in about one third of cases it may be unknown, where the probable origin might be a congenital dural defect. The pathology may show characteristic and misleading MR patterns of the thoracic spine, emphasising the importance of these patterns. This anomaly can lead to progressive Brown-Sequard syndrome. Surgical intervention, consisting the repair of the dural defect may result in improvement or even complete regression of the neurologic deficits.
Insights
Transdural spinal cord herniation, though rare, can be misdiagnosed. Surgical repair of the dural defect may improve or resolve neurological deficits, such as Brown-Sequard syndrome.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Transdural spinal cord herniation is a rare condition.
- It is often misdiagnosed due to its rarity and misleading imaging findings.
- Potential causes include iatrogenic injury, trauma, or congenital dural defects.
Observation:
- Magnetic resonance (MR) imaging of the thoracic spine can reveal characteristic yet misleading patterns.
- These patterns are crucial for accurate diagnosis.
- The condition can progress to cause Brown-Sequard syndrome.
Findings:
- Congenital dural defects are implicated in approximately one-third of cases.
- The misdiagnosis rate is high.
- Characteristic MR imaging findings are key to identification.
Implications:
- Early and accurate diagnosis is essential for effective management.
- Surgical repair of the dural defect is the primary treatment.
- Surgical intervention can lead to significant improvement or complete regression of neurological deficits.
