Abstract

Background: Susac syndrome (retinocochleocerebral vasculopathy) is an autoimmune endotheliopathy affecting the precapillary arterioles of the brain, retina, and inner ear. It presents with encephalopathy, branch retinal artery occlusions, and hearing loss. The condition is often under recognized because the clinical symptoms may present at different times and physicians may be unfamiliar with the syndrome. Peripheral findings would be helpful in early diagnosis. There are numerous treatment regimens proposed with varying effectiveness. Case presentation: We report the case of a 22-year-old Caucasian man in whom there were prominent skin findings, including livedo reticularis and a micropapular eruption which responded promptly to treatment suggesting that skin involvement may facilitate earlier diagnosis. Rituximab has occasionally been used in more refractory disease. We observed a prompt response to the combination of intravenous immunoglobulin, corticosteroids, and rituximab instituted immediately after diagnosis. Conclusions: A careful search for dermatological manifestations may help with earlier diagnosis. Skin findings may be another marker of endothelial cell involvement. Early use of rituximab as part of the therapeutic regimen may be warranted.
