Abstract
Epilepsy is a complex disease and is caused by a variety of lesions that fall under various aetiologies such as malformative, genetic, infectious, metabolic, immune-mediated and neoplastic aetiologies. Patients’ evaluation and management require an interdisciplinary approach with the involvement of clinical assessment, electrophysiology, imaging and pathology. Definitive surgeries are offered to patients with poor response to anti-seizure medications and to those with a focal lesion.
As Pathologists, we receive tissue samples from surgical resections of the epileptogenic focus. The most common lesions that are diagnosed histopathologically are hippocampal sclerosis, focal cortical dysplasias and neoplasms. This talk will give an overview of the various lesions that a neuropathologist encounters in the surgical samples of epilepsy-related disorders. How the samples are processed and assessed will be illustrated.
