# Acute Spinal Cord Infarction Secondary to Spinal Dural Arteriovenous Fistula: A Rare Cause of Reversible Paraplegia

## TL;DR

A rare spinal dural arteriovenous fistula caused sudden paraplegia, but quick treatment led to partial recovery.

## Contribution

Highlights a rare but treatable cause of acute paraplegia through a case report and successful intervention.

## Key findings

- AV fistula was identified as the cause of acute spinal cord infarction in a 76-year-old male.
- Urgent embolization led to significant recovery of muscle strength despite persistent neurogenic bladder.
- Timely diagnosis and intervention are crucial for managing reversible paraplegia.

## Abstract

Acute spinal cord infarction due to spinal dural arteriovenous (AV) fistula is a rare etiology of acute paraplegia that challenges timely diagnosis. We report a case of a 76-year-old male presenting with sudden bilateral lower extremity weakness, urinary retention, and constipation. Diagnostic evaluation revealed an AV fistula causing spinal cord infarction, confirmed by imaging. Urgent embolization resulted in significant recovery of muscle strength, though neurogenic bladder persisted. This case underscores the importance of identifying reversible causes of acute paraplegia and the critical role of prompt intervention.
