Assessment of CT scans findings in patients with seizures: An Imaging perspective

Epilepsy is a chronic disease characterized by recurrent seizures that affect 2% of the population. The present study was conducted to assess the role of EEG and CT scan in patients with partial or generalized seizures and to make out any correlation between these two investigations and to establish usefulness of CT in defining the aetiology of seizures. The study was retrospectively carried out on the records of patients who underwent CT scan for seizures in Radiodiagnosis Department of the tertiary care hospital in New Delhi. Cases with history of seizure disorder in which EEG was also available were included in the study. EEG and CT scan findings were correlated. Obtained data was arranged accordingly and was expressed as a number and percentage of respondents and were analyzed using the SPSS Version 17 software. Out of 116 total patients, 65were males and 51were females. Out of total 57 patients with partial seizures, 30 showed abnormal CT findings while 27 showed normal CT findings. Out of 59 patients with generalized seizures, 19 showed abnormal CT findings while showed 40 had normal CT findings. Maximum patients showing abnormal CT findings belonged to the age group of 11 to 20 years. Tuberculoma was the most common abnormal CT finding in the present study. Every case of idiopathic partial seizures must be evaluated with EEG as well as CT scan as there are nearly 50% chances of finding some structural cerebral lesion.
