Abstract :

Aim: To study profile of MRI findings in patients with seizure disorder and correlate the MRI findings with clinical type of seizure.

Materials: It was a prospective study in which 150 patients presenting with seizure disorder were evaluated by MRI.

Result: Out of 150 patients, 108 (72%) patients showed abnormalities while 42 (28%) patients revealed no abnormality. Neuroinfection formed the major group (31.3%) followed by neoplasms (17.3%), developmental anomalies (14.7%), hypoxic/ischemic encephalopathy (6%) and Rasmussen�s encephalitis with vascular malformations forming minority (0.7%). In patients with no gross abnormality, 22.2% patients showed unilateral hippocampal sclerosis. Abnormalities were more common in patients with partial seizures than with generalized/absence seizures

Conclusion: MRI not only identifies specific epileptogenic substrates, but also determines specific treatment and predicts prognosis. In this study 72% of patients presenting with seizure disorder showed abnormality on MRI. Hence all patients with seizures should undergo detailed neuroimaging.
