Abstract
Eclampsia remains a principal cause of maternal mortality, especially in low- and middle-income countries. The frequent association with Posterior Reversible Encephalopathy Syndrome (PRES) underscores the critical role of neuroimaging in clinical assessment. We aimed to evaluate tomographic findings in women with eclampsia and analyze clinical factors associated with these abnormalities. This descriptive, retrospective study was conducted at the Hospital Universitario San Vicente Fundación in Medellín, Colombia. A mandatory registry identified women diagnosed with eclampsia between 2011 and 2023. Non-contrast cranial tomography results and clinical data were analyzed using univariate and multivariate logistic regression to determine factors associated with imaging abnormalities. The primary outcomes were the presence of abnormalities on non-contrast cranial CT scans and their association with clinical factors such as antepartum eclampsia and HELLP syndrome. Of the eighty-one women with eclampsia, sixty-seven underwent non-contrast cranial tomography. Abnormal findings were observed in 52% of cases, with 74% consistent with PRES and 22% showing evidence of hemorrhage. Antepartum eclampsia and HELLP syndrome are significantly associated with abnormal imaging findings, with odds ratios of 11,72 (2.34 - 106,23) and 9,14 (1.72 - 85,72), respectively, after adjusting for potential confounding variables. Given the high prevalence of tomographic abnormalities, non-contrast cranial tomography should be considered for all women with eclampsia, particularly those with antepartum presentations or HELLP syndrome. These findings support the need for revising neuroimaging guidelines to improve the diagnosis and management of neurological complications associated with eclampsia, especially in resource-limited settings.
