MRI (magnetic resonance imaging) spectrum of epilepsy

In 361 patients with strong clinical suspicion of secondary epilepsy magnetic resonance imaging (MRI) was performed. Three hundred and forty-five patients revealed a positive study. Maximum number of patients (28.3%) were in the age group of 2 to 12 years without any significant sex predilection. More than 70% patients presented with generalised seizures. MRI revealed definite evidence of tuberculoma in 98, neurocysticercosis in 86, tumour in 60 and cerebrovascular accident in 23 patients. There were 78 patients in miscellaneous group which included patients with magnetic resonance (MR) diagnosis of generalised or focal atrophy, demyelinating disease, hydrocephalus with or without basal exudates, calcification and disappearing lesion. In 16 patients MR was found to be within normal limits.
