# A Case of Aseptic Meningitis Presenting With Widespread Non‐Dermatomal Neuropathic Pain

## TL;DR

A 62-year-old man with ulcerative colitis developed widespread neuropathic pain, which was later linked to aseptic meningitis.

## Contribution

This case report highlights a rare presentation of aseptic meningitis causing non-dermatomal neuropathic pain.

## Key findings

- Aseptic meningitis was confirmed via cerebrospinal fluid analysis and brain MRI.
- The patient's pain improved with oral analgesics.
- Other conditions like vitamin B12 deficiency and cervical spondylotic myelopathy were present but not the cause of the pain.

## Abstract

Aseptic meningitis occasionally causes neuropathic pain in a dermatomal distribution, but widespread non‐dermatomal pain is extremely rare. We report a case of a 62‐year‐old man with ulcerative colitis who developed neuropathic pain involving the head, trunk, and limbs. Cerebrospinal fluid analysis and brain MRI confirmed aseptic meningitis. Although vitamin B12 deficiency and cervical spondylotic myelopathy were present, they did not explain the symptoms. The pain improved with oral analgesics. This case highlights aseptic meningitis as a possible cause of non‐dermatomal neuropathic pain.
