Evaluation of Brain MRI Findings in Patients Referred with Seizures

Abstract

Introduction: Seizures are one of the common and warning signs of brain diseases, which doctors often use CT-scan or MRI for diagnose. The present study was conducted with the aim of evaluation of brain MRI of the patients referred with seizures in order to determine their brain lesions and involvement. Methods: The study was carried out using a retrospective cross-sectional descriptive method. All the patients with seizures referred for MRI to the Radiology Department of Shahid Sadoughi Hospital in Yazd City, Iran during 2016-2020 were examined. By referring to the archives of the radiology department, the records and MRI of the patients referred with seizures were extracted. Then, the data were extracted from the Hospital Information System and the patients' files; after that they were analyzed with SPSS version 16. Results: The present study was conducted on 105 patients with seizures for brain MRI. 48.6% (51 people) of patients were male and 51.4% (54 people) were female. The average age of the patients was 34.17 ± 10.50 years. MRI was normal in 59% of the patients. 16.2% Non-Specific, 6.7% Mass and 4.8% evidence of Encephalomalacia were also reported. The most lesions with 10.5% were related to left frontal lobe and 2.9% were related to right frontal lobe. 99% of seizures were unspecified convulsion and 1% were postprocedural disorder of nervous system. There was no significant relationship between the gender of the patients and their diagnosis (P>0.471). Conclusion: Wide abnormalities such as mass, edema, encephalomalacia and demyelination are observed in the MRI of the patients with seizures and are often located in the frontal lobe. In general, seizures can cause transient and reversible brain abnormalities in MRI.
