Spontaneous Spinal Epidural Hematoma Mimicking Lumbar Disc Herniation

We experienced 5 surgically confirmed cases of spontaneous lumbosacral spinal epidural hematoma. There was no history of major trauma to the lumbar spine, anticoagulant use, or coagulopathy except repeated minor trauma. The clinical findings in spontaneous spinal epidural hematoma were identical to those in acute disc herniation. These cases were combined with diffuse disc bulging and located in one level of intervertebral segment. Etiologic factors, the clinical findings, bleeding source of lumbo-sacral spontaneous epidural hematoma are stressed with review of patient literature.
