Seizure patterns and other clinical features were analyzed in 55 epileptic patients with electrographic evidence of exclusive or predominant occipital involvement. Few statistically significant differences in clinical or ictal patterns were found between subjects with purely focal occipital involvement and those with temporal and temporo-parietal spread or(More)
Four patients with seizures of presumed temporal lobe origin are presented in whom a definite focal ictal onset in the orbitofrontal cortex was revealed during recording, either by chronically implanted electrodes or ECoG. In three cases automatisms occurred concomitantly with orbitofrontal activation without spread of paroxysmal activity into the temporal(More)
Fifty-five patients with intractable partial seizures whose on-medication EEGs demonstrated either predominantly focal epileptiform lesions or absence of paroxysmal activity, were studied, and the effect of withdrawing all anticonvulsive drugs on their EEGs was observed. Four types of response were encountered: (1) no effect (20%); (2) specific (focal)(More)
Four prolonged episodes of partial complex status epilepticus were observed in a teenaged girl. During each there was an "ictal" phase, in which her mental state frequently fluctuated between mildly clouded consciousness and almost total unresponsiveness; once, she was also blind during this phase of impaired consciousness. With therapy, the periods of(More)
This study is based on 28 patients with intractable seizures in whom exclusively extratemporal or a combination of temporal and extratemporal electrodes were chronically implanted for the localization of the epileptogenic process and possible surgical treatment. Clinical and electrographic data are briefly summarized, the indications for the use of(More)
A case of a suprasellar granular cell tumor, approximately 1.5 cm in diameter, in a 68-year-old woman is described. Diagnosis was established postoperatively by histopathological examination of the tumor tissue. The preoperative computed tomographic scan revealed a slightly hyperdense suprasellar mass with strong contrast enhancement. There was no evidence(More)
BACKGROUND AND PURPOSE Technological advances have helped to improve the efficiency of treating patients with large vessel occlusion in acute ischemic stroke. Unfortunately, the sequence of events prior to reperfusion may lead to significant treatment delays. This study sought to determine if high-volume (HV) centers were efficient at delivery of(More)
PURPOSE Advanced neuroimaging techniques may improve patient selection for endovascular stroke treatment but may also delay time to reperfusion. We studied the effect of advanced modality imaging with CT perfusion (CTP) or MRI compared with non-contrast CT (NCT) in a multicenter cohort. MATERIALS AND METHODS This is a retrospective study of 10 stroke(More)
A 20-year-old man suffering from Crohn's disease developed coma and generalized seizures following ileocecal resection. During postoperative parenteral feeding he received xylitol in an unusually high concentration. CT examinations a few days before death showed intense hypodensity and swelling of brainstem and basal ganglia and increasing triventricular(More)
