Background: Spinal cord injury in children is associated with severe morbidity and immense socioeconomic burden. In spinal cord injury without radiologic abnormalities (SCIWORA), magnetic resonance imaging (MRI) can detect intramedullary or extramedullary pathologies or show absence of neuroimaging abnormalities. Pathogenesis of SCIWORA is based on the concept that the inherently elastic paediatric spinal column can afford significant degree of segmental dislocation, resulting in damage of the spinal cord, without any obvious spinal fracture or ligamentous disruption. Case presentation: The medical history of the patient includes only a delayed presentation of unilateral upper extremity weakness to a child after violent traction of neck and upper extremity. A Guilford-type brace was applied to the patient for 3 months and the neurological outcome was eventually relatively uneventful. The clinical and radiologic work-up, combined with the neurological findings, established the diagnosis of SCIWORA, and we are highlighting the clinical and radiological features. Conclusion: Review of the literature, regarding SCIWORA cases, reveals that the recognition of only edema of the spinal cord, without evidence of haemorrhage, as a positive predictive factor. SCIWORA should be included in the differential diagnosis of cases with paresis of the extremities, even though the possible traumatic event may manifest a significant time delay from the clinical sequelae, as it was the case for our patient.
