Susac syndrome in a young child

Area of Science:

• Neurology
• Radiology
• Ophthalmology
• Otolaryngology

Background:

• Susac syndrome is a rare microangiopathy affecting the brain, retina, and inner ear.
• It is often misdiagnosed as demyelinating conditions like multiple sclerosis.
• A high index of suspicion is crucial as patients may not present with the full triad initially.

Observation:

• Characteristic MRI findings include multifocal white matter and occasional grey matter lesions, with corpus callosum involvement being constant.
• Predominant central callosal lesions with rapid cystic transformation (central callosal holes) are pathognomonic.
• Susac syndrome is extremely rare in children.

Findings:

• This case highlights Susac syndrome in a 9-year-old girl, a demographic rarely considered for this condition.
• The report aims to raise awareness among pediatric radiologists about this rare entity.
• The study emphasizes the importance of considering Susac syndrome in the differential diagnosis of multifocal white matter lesions in children.

Implications:

• Increased awareness can lead to earlier diagnosis and appropriate management of Susac syndrome in pediatric patients.
• Recognizing characteristic MRI features can help differentiate Susac syndrome from other neurological conditions.
• This case contributes to the understanding of Susac syndrome's presentation in a pediatric population.
