Epilepsy can be a progressive and debilitating illness in the pediatric population. There is a large range of congenital conditions that present with seizures in neonatal patients, which are essential for the radiologist to accurately characterize on imaging. Accurately diagnosing the cause of epilepsy can not only allow appropriate treatment, but also provide important information on prognosis and associated abnormalities.

The goal of this educational poster is to provide an overview of different congenital etiologies of epilepsy. This case based review includes congenital malformations of the brain such as focal cortical dysplasia, schizencephaly, heterotopias, hemimegalencephaly, and polymicrogyria. Cases highlighting neurocutaneous conditions associated with epilepsy including tuberous sclerosis and Sturge-Weber are reviewed. Cortical injuries from insults such as congenital infection, hypoxic-ischemic injury, or hemorrhage are also included.

Familiarity with the imaging findings of epilepsy is essential for the radiologist, especially the trainee and those with less experience with pediatric neuroimaging. After reviewing this educational poster, viewers will be able to describe the imaging features of congenital causes of epilepsy and understand the treatment and prognoses of these conditions.

The goals of this educational exhibit are to: 1. Explain the basis for the cause of diffusion restriction on brain MRI in children. 2. Discuss the broad differential diagnosis for diffusion restriction in pediatric emergency neuroradiology. 3. Emphasize causes of diffusion restriction unrelated to vascular occlusive disease in the brain. 4. Describe patterns of diffusion restriction commonly encountered in post-ictal states and posterior reversible encephalopathy syndrome. Read More

The goal of this educational exhibit is to explore the utility of interictal FDG PET brain imaging in the evaluation of intractable, drug-resistant cases of pediatric epilepsy and to clarify its role in pre-surgical seizure focus localization. We will also explore the salient pearls and pitfalls of FDG PET brain imaging. Read More

Single stage corpus callosotomy is a surgery utilized in patients with intractable epilepsy that prevents the spread of seizure impulses to the contralateral hemisphere. This study aimed to evaluate post corpus callosotomy findings on fluorodeoxyglucose (FDG) positron emission tomography (PET)-computed tomography (CT), specifically a finding noted in which a cerebral hemisphere demonstrated new (compared to baseline PET-CT) hypometabolism without corresponding magnetic resonance imaging (MRI) lesion. Our aim was to determine if this finding had clinical relevance in predicting post procedure seizure rates. Read More
