Summary
A permanent epidural catheter caused dural sac pressure, mimicking metastasis. Epidurography confirmed the catheter
Area of Science:
- Medical Case Report
- Neurosurgery
- Pain Management
Background:
- Continuous analgesia is often managed with epidural catheters.
- Encapsulated permanent epidural catheters are used for long-term pain relief.
Observation:
- A patient developed symptoms suggesting epidural metastasis.
- Clinical presentation and imaging (postmyelographic CT) were consistent with metastasis.
Findings:
- The patient's symptoms were caused by an encapsulated permanent epidural catheter.
- The catheter exerted pressure on the dural sac.
Implications:
- Diagnostic imaging can be misleading in cases of epidural catheter complications.
- Epidurography is crucial for accurate diagnosis of catheter-related issues.
- This case highlights the importance of considering device-related complications in differential diagnoses.
