Spontaneous Spinal Subdural Hematoma: Treatment with Lumbar Drainage

ABSTRACT

We report a rare case of spontaneous spinal subdural hematoma(SSDH). A 63-year-old man presented with radicular pain and paraparesis on both legs for several months. On magnetic resonance images, SSDH was found in lumbar region. Electrodiagnostic report showed bilateral lumbosacral polyradiculopathy, such as cauda equina syndrome. SSDH was drained with lumbar drainage at L4-5 level without direct exploration. The patient improved after drainage of the hematoma and then he was able to walk independently.
