RATIONALE We describe seizure and neuropsychological outcome obtained after CAH in patients with TLE and normal MRI evaluated in the modern imaging era. METHODS Forty-five adult consecutive patients with TLE and normal MRI were studied. All patients had neuropsychological testing, interictal and ictal EEG recordings and MRI. They were divided into two(More)
PURPOSE To study the efficacy of extensive coverage of the brain surface with subdural grids in defining extratemporal cortical areas amenable for resection in patients with refractory extratemporal epilepy (R-ExTE) and normal or nonlocalizing magnetic resonance imaging (MRI) scans. METHODS Sixteen patients with R-ExTE were studied. Eleven patients had(More)
PURPOSE The introduction of new technologies in the clinical practice have greatly decreased the number of patients submitted to invasive recordings. On the other hand, some patients with refractory temporal lobe epilepsy have normal MR scans or bilateral potentially epileptogenic lesions. This paper reports the results of invasive neurophysiology and(More)
PURPOSE To study the seizure's outcome in patients with refractory epilepsy and normal MRI submitted to resections including the rolandic cortex. METHODS Four adult patients were studied. All patients had motor or somatosensory simple partial seizures and normal MRI and were submitted to subdural grids' implantation with extensive coverage of the cortical(More)
OBJECT The authors conducted a study to assess the efficacy of surgery in patients who underwent magnetic resonance (MR) imaging alone for localization of foci in temporal lobe epilepsy (TLE). METHODS One hundred patients (43 men, 57 women) with a clinical diagnosis of TLE were prospectively studied (mean age 28 +/- 9 years [+/- standard deviation {SD}]).(More)
INTRODUCTION Although some degree of bilateral hippocampal involvement might be frequent in patients with temporal lobe epilepsy, severe bilateral mesial temporal sclerosis (MTS) is very rare. We present our experience while treating patients with severe bilateral MTS submitted to invasive recordings. METHODS Nine adult patients were studied. All patients(More)
INTRODUCTION Several pre-operative work-up protocols have been used while selecting epileptic patients for surgery among different centers. The relative value of the different available pre-operative tests is still under discussion. OBJECTIVE We report on the surgical outcome obtained in patients with refractory temporal lobe epilepsy associated to mesial(More)
Hemimegalencephaly (HME) is a rare congenital brain malformation of unknown etiology. Patients with HME can present with an early onset epileptic syndrome which is often refractory to medical treatment and associated to impaired neurological development. Functional hemispherectomy (FH) has proven to be a valuable treatment alternative in patients with(More)
Epileptogenic area in the sensorimotor cortical representation of tongue. Case report treated by surgery We report the case of a 22 year-old male patient with an epileptic focus located at the sensorimotor area of the tongue who was evaluated with subdural electrodes and submitted to a subpial cortical resection. He had seizures characterized by head(More)
A 16-year-old female patient had myoclonic epilepsy caused by Lafora's disease. Muscle biopsy showed a prominent splitting pattern in muscle fibers with the nicotinamide adenine nucleotide dehydrogenase-tetrazolium reductase reaction, hematoxylin-eosin, and PAS stains. This morphologic appearance of the tissue permits diagnosis using the benign technique of(More)
