Popis: OBJECTIVE: To (1) determine the prevalence and type of sepsis-related neuroimaging abnormalities evident on clinically-indicated brain magnetic resonance imaging (MRI) in children with sepsis and (2) test the association of these abnormalities with mortality, new disability, length of stay (LOS), and MRI indication. DESIGN: Retrospective cohort study. SETTING: Single, large academic pediatric intensive care unit (PICU). PATIENTS: Pediatric patients with sepsis between 1/1/2012 and 6/30/2018 with a clinically-indicated brain MRI obtained within 60 days of sepsis onset. MEASUREMENTS AND RESULTS: Two radiologists systematically reviewed the first post-sepsis brain MRI and determined which abnormalities were sepsis-related by consensus. Standard descriptive statistics were used to compare outcomes of PICU mortality, new disability, and PICU LOS in patients with versus without sepsis-related MRI abnormalities. 140 patients underwent clinically-indicated brain MRI within 60 days of sepsis onset. PICU mortality was 7%. Thirty patients had ≥1 sepsis-related MRI abnormality yielding a prevalence of 21% (95% CI 15%, 28%). Among those patients, 53% (16/30) had sepsis-related white matter signal abnormalities, 53% (16/30) sepsis-related ischemia, infarction, or thrombosis and 27% (8/30) sepsis-related posterior reversible encephalopathy. Patients with ≥1 sepsis-related MRI abnormality had increased mortality (17% vs 5%; p=0.04), new neurologic disability at PICU discharge (32% vs 11%; p=0.03) and longer PICU LOS (median 18 vs 11 days; p=0.04) compared to patients without sepsis-related MRI abnormalities. CONCLUSIONS: In children with sepsis and a clinically-indicated brain MRI, twenty-one percent had a sepsis-related MRI abnormality. Sepsis-related MRI abnormalities were associated with increased mortality, new neurologic disability, and longer PICU LOS.
