Symptomatic epileptogenic lesions.
BACKGROUND AND OBJECTIVES The main aim of this study is to prove the association of seizure types with the MRI findings of the brain (etiological factor). Also, to prove which type of lesion is mostly represented in which age-group, and with which type of seizure. METHODS A total of 100 patients with symptomatic epilepsy, aged from 16 to 80 years, were hospitalized at the Neurology Clinic or ...
متن کاملCorrelation of MRI and histopathology in epileptogenic parietal and occipital lobe lesions
INTRODUCTION To analyze the diagnostic accuracy of MRI in patients undergoing parietal and occipital lobe epilepsy surgery. METHODS In a retrospective study, we analyzed MRI scans and neuropathology reports of 42 patients who had undergone resective epilepsy surgery in the parietal and occipital lobe between 1998 and 2003. We evaluated, whether lesions were precisely characterized by MRI and ...
متن کامل[Histopathologic features of glia in human epileptogenic brain lesions].
Focal cortical dysplasia is a common pathologic background observed in surgical specimens taken from patients with intractable epilepsy, where various types and degrees of dysplastic features were observed in various combinations. Prominent astrocytosis in the cortex and white matter was commonly evident. An ultrastructural investigation revealed dilatation of the postsynaptic dendritic spines ...
متن کاملDetection of Epileptogenic Cortical Malformations with Surface-Based MRI Morphometry
Magnetic resonance imaging has revolutionized the detection of structural abnormalities in patients with epilepsy. However, many focal abnormalities remain undetected in routine visual inspection. Here we use an automated, surface-based method for quantifying morphometric features related to epileptogenic cortical malformations to detect abnormal cortical thickness and blurred gray-white matter...
متن کاملEpileptogenic Lesion Quantification in MRI Using Contralateral 3D Texture Comparisons
Epilepsy is a disorder of the brain that can lead to acute crisis and temporary loss of brain functions. Surgery is used to remove focal lesions that remain resistant to treatment. An accurate localization of epileptogenic lesions has a strong influence on the outcome of epilepsy surgery. Magnetic resonance imaging (MRI) is clinically used for lesion detection and treatment planning, mainly thr...
