Spontaneous Spinal Subdural Hematoma causing Brown-Séquard Syndrome with Thrombocytopenic Myelodysplastic Syndrome

摘要

Spontaneous spinal subdural hematoma (SSDH) is a very rare condition. We report a case of SSDH presenting with Brown-Séquard syndrome, treated by surgical evacuation. A 77-year-old woman was hospitalized for back pain without trauma history. As she showed progressive sensory loss and right-side dominant paraparesis, we performed magnetic resonance imaging and confirmed the SSDH in the thoracic area. Therefore, she underwent emergent operation and the hematoma was evacuated successfully. After the operation, the patient showed improvement in neurologic function.
