AI Summary
A patient with MS developed acute asymmetric visual field loss due to a chiasmal colloid cyst, highlighting that new visual defects aren't always MS-related and require thorough investigation.
Abstract
Purpose
To report a patient with multiple sclerosis and a history of sequential bilateral retrobulbar neuritis, who developed new onset of highly asymmetric upper quadrantanopsia.
Design
Interventional case report.
Method
A 36-year-old woman with multiple sclerosis and bilateral retrobulbar neuritis developed an acute asymmetric upper nasal quadrantanopsia.
Results
Magnetic resonance imaging of the brain revealed a cyst that caused chiasmal compression and bilateral visual field defects.
Conclusion
New onset of bilateral visual field defects in a patient with diagnosed multiple sclerosis is likely to be caused by a new attack of the demyelinating disease. In this case, a newly diagnosed chiasmal colloid cyst was the cause of visual field defects.
