• Spinal cord hemorrhage is rare when compared to cerebral hemorrhage and usually arises from trauma (ex. acceleration/deceleration injury), vascular malformations or bleeding disorders (particularly due to administration of anticoagulants)
• Hemorrhage can result in ischemia of the involved segment leading to necrosis (below); clinical signs and symptoms of an intramedullary hemorrhage include sudden, severe, localized back pain with or without radicular pain, hemi-, para- or quadriparesis, sensory loss below the lesion
• Extension of the lesion can lead to subarachnoid or subdural or epidural hemorrhage. The latter two cause compressive symptoms due to presence of hematomas in subdural or epidural space.
