A Rare Case of Susac's Syndrome Masquerading as Progressive-Relapsing Multiple Sclerosis

Area of Science:

• Neuroscience
• Immunology
• Ophthalmology

Background:

• Susac's syndrome (SS) is a rare autoimmune vasculitis affecting the central nervous system (CNS), retina, and cochlea.
• It classically presents with encephalopathy, visual loss, and hearing loss, but this triad is rarely observed in its entirety.

Observation:

• This report details a case of SS in a young male initially misdiagnosed as multiple sclerosis (MS).
• The clinical presentation, laboratory findings, and imaging results of SS can significantly overlap with MS, complicating diagnosis.

Findings:

• Differentiating SS from MS is crucial for appropriate treatment and management.
• Key differences between SS and MS are reviewed to aid physicians in accurate diagnosis.

Implications:

• Early and accurate diagnosis of SS is essential to prevent irreversible neurological damage.
• Understanding the distinctions between SS and MS allows for tailored treatment strategies, improving patient outcomes.
