Real Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) in Pediatrics: A Clinical Case Report and Literature Review.

ABSTRACT

Spinal cord injury without radiological abnormality (SCIWORA) was first reported in 1974. The term was used to define "clinical symptoms of traumatic myelopathy without signs of fracture or spine instability on X-ray or CT scan." With the emergence of MRI, the gold standard method to identify spinal cord injuries, about two-thirds of former SCIWORA cases were found to have pathological findings, and, as such, the term has taken on an ambiguous meaning in the literature. We describe the clinical case of a 17-year-old boy who was admitted to the emergency department of a tertiary hospital after a fall during a soccer game. He suffered spinal and cranioencephalic trauma. A few minutes later, the boy began to show decreased strength in the right upper limb and lower limbs, as well as changes in sensation in the right hemibody. On objective examination, the boy presented a Glasgow Coma Scale score of 15 and the American Spinal Injury Association Impairment Scale D, with partial improvement of initial symptoms of monoparesis of the right lower limb. There were no other changes, specifically at the sensory level. The patient underwent a CT and MRI of the spine that showed no fractures, instability, or appreciable medullary signal changes. Electromyography was normal. Based on the clinical history and imaging findings, real SCIWORA was diagnosed. The patient was admitted to an inpatient rehabilitation program. At a follow-up visit two months later, a complete reversal of signs and symptoms was confirmed. The prognosis of this pathology depends on the extent of the spinal cord injury, as evidenced by MRI. Although neurological improvement when severe deficit is present at initial presentation is unlikely, most patients with incomplete neurological damage show good recovery. The absence of visible changes on MRI is associated with a better prognosis.
