Spontaneous spinal epidural hematoma (SSEH) is a rare but real neurosurgical emergency. It is caused by atraumatic rupture of the vertebral epidural vein that results in nerve root or spinal cord compression. Most cases of SSEH have a multifactorial etiology, including congenital and acquired coagulopathies; platelet dysfunction; vascular malformation; tumors; uncontrolled hypertension; pregnancy; and, very rarely, activities requiring Valsalva. ⋯ Playing the piano is a joyful, relaxing entertainment; however, this musical activity can be a highly demanding physical and mental exercise for pianists. Emotional and expressive performance, especially in professional performing, has been reported to result in significant increase of sympathetic and decrease of parasympathetic activities and thus influence the cardiorespiratory variables. The increased biomechanical stress from fluctuating hemodynamics was thought to trigger the rupture of her spinal arteriovenous malformation.
