Spontaneous spinal epidural hematoma (SSEH) is an extremely rare complication in the postpartum period. SSEH in thoracic spine after natural delivery has never been reported. A 25-year-old women presented with acute onset of paraplegia eight hours after normal vaginal delivery. MRI revealed a right lateral mass in the thoracic spinal canal extending from T1 to T2. Prompt decompressive laminectomy was performed within 12 hours after the event. Follow-up at one month post-operation showed a favorable neurological outcome of the patient. In addition, literatures of similar SSEH cases during pregnancy and postpartum period were reviewed, aiming to highlight the importance of early recognition and expedient intervention of SSEH.
