Summary
A patient experienced prolonged aseptic meningitis after microvascular decompression for trigeminal neuralgia. Symptoms resolved only after surgical removal of the Teflon padding used during the procedure.
Area of Science:
- Neurosurgery
- Neurology
- Pathology
Background:
- Microvascular decompression is a surgical treatment for trigeminal neuralgia.
- Teflon padding is sometimes used during this procedure to protect the trigeminal nerve.
Observation:
- A 47-year-old male developed persistent aseptic meningitis post-surgery.
- The patient required steroid dependency for 5 months.
- Symptoms of aseptic meningitis resolved only after Teflon removal.
Findings:
- Prolonged aseptic meningitis can be a complication of microvascular decompression.
- Teflon implants may trigger a persistent inflammatory response.
- Surgical removal of Teflon can resolve intractable aseptic meningitis.
Implications:
- This case highlights the potential for delayed adverse reactions to surgical materials like Teflon.
- Consideration of Teflon removal may be necessary for refractory aseptic meningitis post-neurosurgery.
- Further research into the body's reaction to implanted biomaterials is warranted.
