BACKGROUND: Epilepsy is a chronic disorder characterized by a spontaneous tendency for recurrent seizures. An epileptic seizure is a clinical manifestation of abnormal, excessive neuronal activity arising in the grey matter of the cerebral cortex. Epilepsy is one of the most common conditions to be evaluated by MRI.

METHODS:This is Hospital Based Prospective Observational study, conducted in the department of radio-diagnosis, NSCB Medical College and Hospital in conjunction with MP MRI and CT Scan Centre, Jabalpur. This study comprised of a total of 150 patients clinically diagnosed as seizures disorder who had undergone MRI examination.

RESULTS: Cases were divided according to the age ranging from < 1 to 91 years with presenting complaint of seizures. Maximum number of patients was males and in the age group of 16-30 years. MR examination had abnormal findings in 92 out of 150 patients (62%), of which majorly was infective granuloma (35.86%), infarct with gliosis (19.56%), tumours (13.04%), congenital (5.4%), Mets (4.3%), sinus thrombosis (3.2%); miscellaneous causes were 18.47%. GTCS was the most common type with 132 (88%) involving generalized, absence and myoclonic; patients were predominantly males 84 (63.6%), between the age group of 16-30 years.

CONCLUSIONS: From the present study it was noted that MRI is a very efficient tool in diagnosing the aetiology of epilepsy. Identification of the exact location of the epileptogenic focus is of great help from neurosurgical point of view. Diagnosing and characterizing the abnormalities with great accuracy by MRI not only helps in preoperative cases but also helps to evaluate the post-operative status. It is non-invasive and there is no exposure to ionizing radiation.
