Spinal Cord Infarction Diagnostics and Clinical Outcomes

Spinal cord infarction is an uncommon but often devastating form of central nervous system ischaemia, accounting for a small fraction of all strokes yet carrying disproportionately high morbidity. It typically presents with acute motor weakness or paralysis, a distinct sensory level and autonomic dysfunction. Early diagnosis hinges on a combination of detailed neurological assessment and advanced imaging techniques. Conventional magnetic resonance imaging (MRI) may be normal in the hyperacute phase, prompting the use of diffusion-weighted imaging and repeat scanning to reveal characteristic cord changes. Electrophysiological studies such as somatosensory and motor evoked potentials serve as adjuncts, enabling rapid confirmation of disrupted pathways and differentiation from inflammatory or compressive myelopathies. Therapeutic options remain largely supportive, focusing on antiplatelet or anticoagulant therapy, optimisation of spinal cord perfusion and intensive rehabilitation. Clinical outcomes are influenced by the extent and level of infarction, the speed of diagnosis and the effectiveness of early interventions. Recent advances in imaging protocols, electrophysiological monitoring and targeted neuromodulation offer new avenues to refine diagnostics and improve functional recovery, underscoring the global importance of timely recognition and management of this rare vascular emergency.

Technical terms

Diffusion-weighted imaging (DWI): MRI sequence sensitive to the diffusion of water molecules, useful for detecting acute ischaemia. Somatosensory evoked potentials (SEP): Electrical responses recorded from the nervous system following sensory stimulation, used to assess the integrity of sensory pathways. Motor evoked potentials (MEP): Electrical responses elicited by stimulation of the motor cortex or spinal cord to evaluate descending motor tracts. Anterior Spinal Artery Syndrome: Vascular syndrome resulting from ischaemia of the anterior spinal artery, characterised by motor paralysis and loss of pain and temperature sensation. T2-hyperintense lesion: Area of high signal on T2-weighted MRI indicating abnormal water content, often seen in infarction or inflammation.
