# An Uncommon Coexistence of Ischemic Stroke in a Multiple Sclerosis Patient With Duplicated Superior Cerebellar Artery: A Case Report From Saudi Arabia

## TL;DR

A man with multiple sclerosis had a rare stroke due to a duplicated brain artery, showing how unusual anatomy can affect stroke risk.

## Contribution

Reports a rare case of ischemic stroke in a multiple sclerosis patient with a duplicated superior cerebellar artery.

## Key findings

- A duplicated left superior cerebellar artery was identified in a patient with multiple sclerosis.
- The patient's ischemic stroke was linked to this rare anatomical variant.
- The case emphasizes the need to consider vascular anatomy in stroke risk assessment.

## Abstract

The case describes a middle-aged man with well-managed multiple sclerosis who experienced an acute ischemic stroke attributed to a rare anatomical variant - a duplicated left superior cerebellar artery (SCA). Despite his prior lack of neurological issues, the patient presented with severe headaches and walking difficulties. Imaging confirmed the ischemic stroke in the left SCA territory and revealed the duplicated left SCA. This case highlights the importance of considering cerebrovascular anatomy in stroke risk assessment, especially in individuals with unique vascular features such as duplicated SCAs, which can predispose to vascular complications.
