Deteriorating neurological symptoms of Degos disease despite the treatment with eculizumab and beraprost: A case report with detailed radiological findings

Degos disease is a rare vasculopathy with a poor prognosis. Here, we report a case of a 17‐year‐old Japanese male with Degos disease who exhibited progressive deterioration of neurological symptoms despite treatment with eculizumab and beraprost. We also report detailed radiological findings including brain magnetic resonance imaging and perfusion computed tomography, and hereby suggest the importance of the perfusion study in detecting early changes associated with Degos disease.
