Abstract:
We present a 75-year-old man who, for 2 weeks, had progressive pain in both of his thighs when standing straight. MR imaging showed a sequestrated disk fragment, which had a signal intensity similar to that of a herniated disk with a rim enhancement in the posterior epidural space and a ruptured outermost annulus of the intervertebral disk at L2-3. Awareness of these MR imaging findings can help in the diagnosis of posterior epidural disk migration.
Insights
A 75-year-old man experienced thigh pain due to a rare condition: posterior epidural disk migration. Recognizing specific MRI findings is key for diagnosing this unusual cause of back pain.
Area of Science:
- Neurology
- Radiology
- Orthopedics
Background:
- Lumbar disc herniation is a common cause of low back pain.
- Posterior epidural disc migration is a rare variant.
Observation:
- A 75-year-old male presented with a two-week history of progressive bilateral thigh pain upon standing.
- Magnetic Resonance (MR) imaging was performed to investigate the cause of pain.
Findings:
- MR imaging revealed a sequestrated disc fragment in the posterior epidural space at L2-3.
- The fragment exhibited signal intensity similar to a herniated disc with rim enhancement.
- A rupture of the outermost annulus of the intervertebral disc was also noted.
Implications:
- These specific MR imaging findings are crucial for diagnosing posterior epidural disc migration.
- Accurate diagnosis can lead to appropriate management and improved patient outcomes.
- This case highlights the importance of considering rare disc pathologies in the differential diagnosis of spinal pain.
