Spinal Subarachnoid Hemorrhage Migrated from Traumatic Intracranial Subarachnoid Hemorrhage

Very rarely, spinal subarachnoid hemorrhage (SSAH) can occur without any direct spinal injury in patients with traumatic intracranial SAH. A-59-year-old male with traumatic intracranial subarachnoid hemorrhage (SAH) presented with pain and numbness in his buttock and thigh two days after trauma. Pain and numbness rapidly worsened and perianal numbness and voiding difficulty began on the next day. Magnetic resonance imaging showed intraspinal hemorrhage in the lumbosacral region. The cauda equina was displaced and compressed. Emergent laminectomy and drainage of hemorrhage were performed and SSAH was found intraoperatively. The symptoms were relieved immediately after the surgery. Patients with traumatic intracranial hemorrhage who present with delayed pain or neurological deficits should be evaluated for intraspinal hemorrhage promptly, even when the patients had no history of direct spinal injury and had no apparent symptoms related to the spinal injury in the initial period of trauma.
