Spontaneous spinal epidural hematoma presenting as Brown-Séquard syndrome.

Spontaneous spinal epidural hematoma (SEH) is a rare disease. Furthermore, Brown-Séquard syndrome due to spontaneous SEH has been rarely reported. Early detection of spontaneous SEH is not easy because early symptoms are often atypical and neurologic findings are often absent in the early stage. Early diagnosis and urgent surgical management are needed to prevent permanent neurologic deficits. We report a case of a 30-year-old patient who presented with Brown-Séquard syndrome due to spontaneous SEH. The patient has recovered successfully without any complications through surgical decompression within 12 hours of onset.
