ABSTRACT
OBJECTIVES:
The present study aimed to analyse the clinical and neuroimaging features of a consecutive series of adult patients with spinal cord injury without radiographic abnormality (SCIWORA) receiving early magnetic resonance imaging (MRI), and to apply the recently proposed MRI classification system.METHODS:
Grade of neurologic impairment at admission and discharge was reported according to the American Spinal Injury Association Impairment Scale (AIS). A detailed analysis and categorisation of the extra- and intramedullary MRI findings was performed, and the relationship between imaging type and neurological outcome was described.RESULTS:
Twenty-six adult patients (17 male and 9 female) with SCIWORA were identified (mean age of 52 years). The distribution of the initial AIS grade was 8% A (n=2), 19% B (n=5), 31% C (n=8) and 42% D (n=11) at admission and 15% (n=4) C, 58% (n=15) D and 27% (n=7) E at discharge, respectively. Type I SCIWORA was found in 23% (n=6) and type II in 77% (n=20) (IIa 0%, IIb 25%, IIc 75%). The mean improvement of AIS grade in patients with type I lesions was 1.5 (median 1, range 1-3) and 0.9 (median 1, range 0-3) in type II.CONCLUSION:
The findings underline the prognostic role of early MRI for adult patients with SCIWORA and support the use of the recently introduced MRI classification system. LEVEL OF EVIDENCE Prognostic study, level III.
