Pediatric Spinal Cord Stroke: Clinical Presentation, MRI Features, and Suspected Mechanisms.
Article in Neurology. Clinical practice, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesSpinal cord stroke (SCS) is an underrecognized cause of severe acute myelopathy in children that can be misdiagnosed as an infectious or inflammatory process. Limited characterization of clinical and neuroimaging features of pediatric SCS impede timely and accurate diagnoses. Our objectives were to (1) identify clinical and radiologic features of SCS to prompt timely evaluation and accurate diagnosis and (2) gain insight into mechanisms of SCS.
methodsWe conducted a retrospective case analysis of children (<18 years old) diagnosed with SCS at a specialized referral institution between 2010 and 2025. Clinical records, imaging, and laboratory data were reviewed to identify key features of pediatric SCS.
resultsAmong the 56 included patients, 28 were male (50%), and the age distribution was bimodal, with peaks at 1 and 14 years. Pediatric SCS presented with hyperacute onset of motor, sensory, bladder/bowel, and pain symptoms. The lesions were predominantly anterocentral, longitudinally extensive, with the cervical spinal cord being most often affected. Over time from the onset of symptoms, MRI diffusion restriction decreased, while gadolinium enhancement increased. CSF profile was noninflammatory in 95% of cases. Suspected mechanisms were identified in 63% of cases, with vascular compression being the most commonly identified mechanism in 17 participants (30%), while 38% were idiopathic. Chiari I malformations were identified as the main suspected cause of vascular compression, occurring in a subgroup of young patients with cervical SCS (n = 8, 14%). Serum studies identified hypercoagulability in 38% of the 40 participants evaluated. DISCUSSION: Recognition of specific clinical and neuroimaging profiles in pediatric patients with SCS may facilitate earlier identification and intervention. We propose a systematic evaluation of clinical history, with particular attention to the temporal course from symptom onset to nadir, early acquisition of spine MRIs with diffusion-weighted imaging sequences, serologic evaluations for hypercoagulability, and CSF studies to exclude inflammatory etiologies. This approach will provide a framework for continued efforts to better understand the mechanisms underlying pediatric SCS and develop prevention and treatment strategies.
