STUDY DESIGN: We present a very rare case of an infant with delayed presentation of spinal cord injury without radiologic abnormality (SCIWORA) after a minor injury.
OBJECTIVE: To emphasize the importance of spinal evaluation with MRI in selected cases, even after minor injuries, especially in infants.
SUMMARY OF BACKGROUND DATA: SCIWORA arises mainly in infants and children during accidental trauma or after sport injury. However, it has been very rare for a 6-day-delayed infant SCIWORA after a minor injury.
METHODS: An infant presented with transient nausea and vomiting after falling from a baby-rocking horse of less than 30-cm height. The patient demonstrated right hemiparesis 6 days later. Plain cervical radiographs and brain and cervical spine computed tomograms (CT) were normal, but the cervical magnetic resonance imaging (MRI) demonstrated a high signal in the T2-weighted image of the lower cervical cord, and a neck collar was applied.
RESULTS: A follow-up cervical MRI 1 month later showed that the high signal of the lower cervical cord had disappeared. Another follow-up cervical MRI 12 months later also showed normal radiographic findings but there still remained mild weakness of the right lower extremities.
CONCLUSION: The authors present a rare case of infant SCIWORA who developed delayed neurologic symptoms 6 days after a minor injury and suggest that spinal evaluation with MRI could be warranted in the selected case even after minor injuries, especially in infants.
