Abstract

Objectives: Describe magnetic resonance imaging (MRI) of acute transverse myelitis in children. Method: This is a cross-sectional study including 47 patients with acute transverse myelitis in the Neurology Centre of National Children’s Hospital from June 1^st 2018 to May 31^st 2023. Results: 47 patients met the study criteria. Mean age of onset was 8.3 ± 4.3, female/ male ratio was 1/1.61. The mean interval between symptom onset and the spinal magnetic resonance imaging was 5 days. Spinal MRI showed that mean length of individual spinal lesions was 8.1±5.5, a majority (91.5%) had longitudinally extensive transverse myelitis, the most frequently involved region was the cervical spine. Characteristic lesions of acute transverse myelitis on spinal MRI: T2W hyperintensity (95.7%), gadolinium enhancement (57.8%). Asymptomatic brain MRI lesions showed 23% patients. Conclusion: Spinal MRI is the most accurate imaging method in diagnosing acute transverse myelitis in children: determining the location, extent of the lesions to help the doctors to have diagnosis, prognosis of disease progression and plans for long-term follow-up.
