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.

Functional MRI (fMRI) for preoperative language mapping of Wernicke’s and Broca’s areas in clinical pediatric epilepsy presents various challenges resulting in poor patient compliance. We hypothesized that higher fMRI success rates can be achieved using intensive patient preparation in a fMRI practice session using a mock MRI scanner. Read More

Purpose: The evaluation of epileptic foci with FDG PET can be challenging, particularly when epileptic foci are subtle. We sought to determine if an age-matched database of normative cerebral FDG PET uptake can be used to automatically identify epileptic foci. 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

Epilepsy can be a progressive, debilitating illness, particularly in the pediatric population. More than half of brain tumors are associated with epilepsy, and 30% of these tumors will not respond to pharmacologic therapy. Recognizing lesions that cause seizures is imperative, as providing an accurate diagnosis can identify patients with surgically treatable disease. In the appropriate patient population, epilepsy surgery can be an effective management option that prevents significant morbidity and mortality from epilepsy and dramatically improves quality of life.
This electronic poster will provide an overview of pediatric epileptogenic tumors including gangliogliomas, dysembryoplastic neuroepithelial tumors, pleomorphic xanthoastrocytoma, papillary glioneuronal tumor, pilocytic astrocytoma, and oligodendroglioma. Cases featuring these tumors and their distinguishing characteristics will be reviewed, as both tumor subtype and location contribute to the epileptogenicity of pediatric brain tumors.
The goal of this poster is to provide a framework for the evaluation of pediatric epileptogenic tumors to establish a focused differential diagnosis when these lesions are identified. This is particularly important for trainees and well as those who do not commonly encounter epileptogenic tumors in their practice. 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

Within the last several years there have been updates and changes to the clinical terminology in epilepsy, as well as the histopathologic classification of hippocampal sclerosis and focal cortical dysplasia. The purpose of this exhibit is to review these changes and illustrate them with corresponding MR examples. Read More
