Imaging of infective causes of childhood epilepsy

Pranjit Thapa, Dibyajyoti Nath, Sumit Ujawane


Introduction: A seizure or convulsion is a paroxysmal, time limited change in motor activity and/or behaviour that results from abnormal electrical activity in the brain. Epilepsy is a chronic condition characterized by recurrent seizures unprovoked by an acute systemic or neurological insult. Radiological evaluation of seizures done mainly by computed tomography (CT) & magnetic resonance imaging (MRI). MRI has been shown to be superior to CT for the detection of cerebral lesions associated with epilepsy. The advantage of CT lies in its wider availability, lower costs, less time (helpful in emergency) and compatibility with metallic implants in the patient. Aim : of the study was to evaluate causes, to elucidate infective causes of epilepsy by CT and MR Imaging, to characteristics of the different infective causes. Materials & methods: It was an observational study on 20 patients carried out in the Department of Radiodiagnosis, Silchar Medical College & Hospital, Silchar from August 2014 to July 2015 under 15 years of age using CT and MRI . Results: Adoloscents constituted 6 (30 % ) of the total 20 patients, most are males 15 ( 75 %). Inflammatory granuloma constituted 10 ( 50% ) of the cases, HSV encephalitis 3 ( 15 %) , Japanese encephalitis 2 ( 10 %). Active form of NCC constituted the predominant granulomas ( 50 %), followed by tuberculoma ( 30 %) and calcified NCC ( 20%) on MRI. Solitary granuloma constitute 60% of patients , followed by multiple ( 40%). Mild ventriculomegaly constituted commonest feature of pyogenic meningitis Conclusion: Radiological imaging in the form of CT and MRI play a vital role in etiological evaluation in cases of epilepsy. MRI is the first choice in case of epilepsy. MRI is also recommended, as it is a radiation free modality, however CT is superior in identifying calcified lesions. Infections constitutes one of the important cause of epilepsy .
