# Transient cortical weakness following cerebral angiography: A new syndrome

## TL;DR

This paper describes a new syndrome called transient cortical weakness, which occurs after cerebral angiography and affects the brain's anterior circulation.

## Contribution

The paper introduces transient cortical weakness as a novel clinical entity distinct from transient cortical blindness.

## Key findings

- Transient cortical weakness affects the anterior circulation and has distinct symptoms and imaging findings.
- It is differentiated from common post-procedural complications like stroke or TIA.

## Abstract

Transient cortical blindness is a known complication of iodinated contrast administration and is believed to reflect osmotic injury or autoregulatory dysfunction of the posterior circulation. Here, we report 2 cases of postangiography transient cortical weakness, a rare clinical analog to transient cortical blindness that affects the anterior circulation. The symptoms, timeline, and imaging findings of transient cortical weakness are distinct from more common post-procedural complications such as acute ischemic stroke or transient ischemic attack.
