Kognitiv dysfunktion, synstab og hørenedsættelse kan være Susacs syndrom

This is a case report of a 56-year-old male patient with Susac syndrome. The syndrome is a rare immune-mediated, ischaemic, occlusive microvascular endotheliopathy affecting the brain, retina and inner ear. Diagnosis and treatment are challenging, since the presentation shows great variability. Brain MRI, fundoscopy and audiometry enable the diagnosis. Early treatment with immuno-suppressive medication is crucial and can reduce complications like dementia, loss of visual acuity and hearing. The treatment is empirical and based on the fact, that the histopathology of the syndrome is similar to juvenile dermatomyositis.
