Overview
Key CT Findings for Acute retinal necrosis
CT imaging may reveal indicators of inflammation and infection by the causative pathogen for Acute retinal necrosis (ARN).[1]
- Hypoattenuation along the optic tract indicative of Varicella-zoster virus (VZV) infection.
- Hyperattenuation along the optic tract, retina, sclerae, and lateral geniculate body, indicating presence of lesions indicative of ARN.[2]
- Infection-caused shrunken left globe.
