Abstract

Background: This study focused on imaging findings about magnetic resonance imaging of the brain in patients with seizures. This is an abnormal electrical activity in the brain that can cause temporary or permanent symptoms; therefore, a brain MRI is performed to detect occupant injuries or morphological alterations. (1) Objective: To identify the prevalence of imaging findings in brain MRI in patients aged 5 to 60 years with seizures who received medical care at Medimagen, in Cuenca, Ecuador, from January 2017 to January 2023. Method: The study was descriptive, cross- sectional, and retrospective. The universe comprised the patients who met the inclusion criteria. Radiological reports from the database of Medimagen, Cuenca, then an analysis was carried out using IBM SPSS Statistics 21 v.26 and Excel. Results: 72% of 272 patients reported imaging findings. Most of them were men (54%), and the most affected age group was that of 13 to 20 years (19.7%). The most common findings included tumors and infections (18.7%) and focal cortical dysplasia (14.1%). The temporal lobe (33.3%) and the parietal lobe (23.2%) were the most frequent locations of findings. Conclusion: Positive brain MRI findings in patients with seizures were more frequent in men aged 13 to 20 years with location in the temporal lobe. MRI showed sensitivity (20%) and specificity (69%) in patients with seizures.
