Assessment of Paediatric Seizure Disorder using Magnetic Resonance Imaging of Brain

Introduction: The clinical presentation and type of seizure disorder vary significantly with age and neurodevelopmental maturity. Magnetic resonance imaging (MRI) is the preferred modality for identifying underlying causes, particularly in partial seizures. It enhances the detection of intracranial lesions, especially vascular and meningeal abnormalities. This study aims to assess the role of MRI in evaluating paediatric seizure disorders. Methodology: Seventy-five paediatric patients under 12 years presenting with generalized, partial, or absent seizures underwent MRI. Diagnosis relied on radiological features, supplemented by follow-up MRI and treatment response in inconclusive cases. Result: Generalized seizures predominated (68%), compared to focal seizures (24%). MRI revealed abnormalities in the majority of cases (73.3%). Anoxia and hypoxic-ischemic encephalopathy (41.8%) were the most common aetiologies. Neoplasms were identified in 3 patients: 2 with unspecified types and 1 each with DNET and Pilocytic astrocytoma. Conclusion: MRI plays a crucial role in diagnosing paediatric seizure disorders, facilitating accurate treatment decisions by identifying underlying causes.
