A study to know etiology and spectrum of MRI findings in patients with seizures in tertiary care hospital, Karnataka

Abstract

Background And Objectives: Seizure is a common medical disorder and neuroimaging plays valuable role in evaluation of etiological factors for seizures. The objectives are to identify structural abnormalities in the brain that may be associated with the cause of seizures with MRI and to study the spectrum of findings in patients with seizures. Materials and Methods:- All the cases referred to department of radiology, Sapthagiri institute of medical sciences and research Centre College, Bengaluru, Karnataka. All MRI scans were performed on a 1.5 T Philips Achieva. Sequences used , T1WI sagittal, T2WI axial and coronal, FLAIR axial, gradient echo axial, DWI axial and ADC maps, T1W with contrast, MRA and MRS according to MR Imaging protocol of seizures. Results: In our study 60 patients with clinical diagnosis of seizures were selected as per the criteria laid down by ILAE 1981.Majority of the subjects 28.3% were in 1-15yrs age group, followed by 20% were in 16-30yrs age group, 16.7% were in <1yrs and 31-45yrs age group. Male 35 (58.33%) and Female 25(41.64%).The MR examination revealed pathological findings in 30 out of 60 patients (50%) which includes, cerebral infarct with gliosis (20%), NCC (6.66%), atrophy (6.66%), gliomas (1.66%), cortical malformations (3.34%),tuberculoma (3.34%),venous thrombosis (3.34%), cavernoma (3.34%), meningioma (1.66%)
