Study DesignA case report.ObjectiveWe report a case of spontaneous spinal epidural hematoma with 3 bleeding episodes and discuss the surgical management of recurrent spontaneous spinal epidural hematoma.Summary Of Background DataSpontaneous spinal epidural hematoma is a rare condition that causes spinal cord compression and neurological deficits. However, the cause of bleeding remains unclear and recurrent bleeding is very seldom reported.MethodsA 39-year-old female patient was referred to Kyoto University hospital with sudden back and right upper extremity pain. She was also treated conservatively at the local hospital 19 and 4 months previously because of same episodes. Magnetic resonance images demonstrated right spinal epidural hematoma at the C6-T1 level. In the first 2 episodes, magnetic resonance images revealed spinal epidural hematomas at exactly the same level.ResultsIn the third episode, the patient's neurological condition was not worse than it had been in the first 2 episodes, and we initially managed her conservatively. To identify the cause of the hematoma, surgery was performed 15 days after the third onset. Microscopic examination revealed the development of a venous plexus around the old hematoma in the dorsal epidural space. The patient was discharged without any further neurological deficits, and recurrent bleeding has not occurred for 6 months after surgery.ConclusionThis is the first report of operative and histological observation of recurrent spontaneous spinal epidural hematoma caused by a posterior venous plexus. In a case of recurrent spontaneous spinal epidural hematoma, surgery might be necessary to prevent further hematomas.Level Of EvidenceN/A.
