Magnetic resonance imaging allows the identification of heterotopic gray matter (HGM) in medically intractable partial epilepsies. The relationships between HGM and the epileptogenic zone remain, however, unclear. In a case of a temporo-parietal epilepsy studied by stereo-EEG, interictal and ictal electrical activity of a temporal HGM were recorded,(More)
Patients having a hypothalamic hamartoma frequently present epileptic attacks of laughter, and they later experience multiple additional seizure types, which invariably lead to a severe drug-resistant epilepsy. If this association is now well-known, relationships between the hypothalamic mass and the different types of seizures remain still mysterious. We(More)
In this report we describe three patients with developmental cortical abnormalities (generally referred as cortical dysplasia), revealed by MRI and operated on for intractable epilepsy. Tissue, removed for strictly therapeutic reasons, was defined as the epileptogenic area by electroclinical data and stereo EEG (SEEG) recordings. Tissue samples were(More)
PURPOSE To evaluate lesions of the different structures of the Papez circuit in association with hippocampal sclerosis. MATERIAL and methods. 13 patients (32.1+/-8.2 y.o.) suffering from partial, temporal lobe, drug-resistant epilepsy and 20 normal volunteers (31.8+/-7.7 y.o.) were evaluated by MRI on a 1.5 T scanner (Philips): axial T1w 3D Gradient Echo(More)
Mechanical studies have shown the major strength of the joint capsules of the lower cervical spine, especially in its ventrolateral part. The aim of this study was to examine the structure of the joint capsules in order to discover if there is a correspondence between biomechanical properties and descriptive anatomy. Ten transverse sections and 4 sagittal(More)
A structural lesion of the brain is a frequent finding in intractable partial epileptic patients. We analyse anatomo-electro-clinical characteristics of 58 patients in which MR showed a lesion inside the temporal lobe. They are 29 males and 29 females with a mean age at surgery of 23.5 +/- 10.7 years (2.6-45.9). The mean epilepsy duration is of 13.4 +/- 8(More)
