# Case Report: Intradural gout tophi without systemic gout symptoms

## TL;DR

A rare case of gout tophi in the spinal dura was found in a patient without any signs of systemic gout, highlighting the need for better awareness among doctors.

## Contribution

This is the third reported case of intradural gout tophi in a patient without systemic gout symptoms.

## Key findings

- A 70-year-old woman had a calcified intradural lesion at L3 confirmed as gouty tophi after surgery.
- None of the three reported cases of intradural gout tophi showed systemic gout or high uric acid levels.
- Early diagnosis and surgical removal improved the patient's symptoms significantly.

## Abstract

Gout is a common disease; however, a gout tophus occurring within the spinal dura is exceedingly rare, with only two cases reported to date.

We report the case of a 70-year-old female who presented with lower back pain, right radicular pain, and numbness in the perineal area. Magnetic resonance imaging and computed tomography scans revealed a calcified intradural lesion at the L3 level. The diagnosis of the lesion was not definitive because the patient had no history of gout or manifestations of systemic gout. Surgical removal of the intradural lesion followed by pathological examination confirmed gouty tophi. The postoperative recovery was good, and the patient experienced substantial relief from pain and numbness.

This is the third documented case of gout tophi occurring within the spinal dura. In a literature review, it was found that none of these three patients with intradural gouty tophi had systemic gout manifestations or hyperuricemia, which is a crucial finding. As it is challenging to diagnose intradural gout, awareness among physicians must be increased to optimize the treatment of, and outcomes for, these patients.
