TL;DR: In more than half of the patients a clear-cut general improvement in tests of intellectual performance was found and this indicates that this type of psychomotor epilepsy can be treated more successfully in ths new way than by the classic removal of the temporal lobe or by stereotactic methods.

TL;DR: The different findings from these two examinations are analyzed and a classification of arachnoid cysts of the middle cranial fossa into three basic types is proposed.

TL;DR: Sixty-four of the adenomas were hemorrhagic or had necrotic degeneration and were prolactin-secrets, nonsecreting, growth-hormone-sec reting, or ACTH-LPH-Secreting.

TL;DR: It is suggested that high doses of glucocorticoids can beneficially affect the injured cord through the influence of at least three mechanisms, including a facilitation of neuronal excitability and impulse conduction, an improved blood flow, and a reduction of injury-induced, free radical--catalyzed lipid peroxidation.

TL;DR: All patients with ruptured aneurysms admitted to neurosurgical departments in Denmark after April, 1978, are the subjects in the prospective study that includes neuropsychological examinations, resulting in 6 cases of amnesia.

TL;DR: Thirty-three patients with en plaque, 9 with en masse (but with extensive bone involvement), and 7 with recurrent hyperostosing meningiomas of the sphenoid ridge were operated on, and long-term results have proved to be satisfying.

TL;DR: Dynamic intraoperative imaging of the spinal cord was done using a real-time ultrasound scanner, and the location and extent of intradural extramedullary tumors and tumors that have both extradural andintradural components were demonstrated sonographically.

TL;DR: A case of extrathecal cavernous hemangioma, a rare entity, is presented and the unusual dumbbell-like growth of the tumor through an intervertebral foramen is considered, as well as the potential effectiveness of radiation therapy.

TL;DR: The present study of 11 patients with venous angiomas underscores the clinical importance of these lesions as potential causes of cerebral hemorrhage and obstructive hydrocephalus.

TL;DR: To the authors' knowledge this is the first morphological documentation of spontaneous leakage of cyst contents, and the second report in the English literature of a dense intracranial epidermoid.

TL;DR: A case of spinal intradural arachnoid cyst is presented, and the literature dealing with this rare lesion is surveyed.

TL;DR: All stained tissues obtained in this study demonstrated visible fluorescence within neoplastic tissue margins harboring abnormally permeable blood-brain barriers.

TL;DR: The force/deformation relationship of the exposed spinal cord of cats was studied when the force was gradually applied posteriorly at T10, and the motor function of cats did not recover after the cord had been compressed to 4 mm.

TL;DR: The range and purpose of using an integrated CT-stereotactic system in the assessment of 11 patients with deep brain lesions is described and an accuracy of 1 mm has been achieved.

TL;DR: Two patients with spontaneous carotid-cavernous fistulas were successfully treated with cobalt 60 irradiation to the sellar region, with disappearance of the fistulas on angiograms and patency of the internal and external carotids arteries.

TL;DR: The results of this analysis show that bilateral epidural hematomas may develop slowly indicate that they occur with traumatic forces predominantly oriented in the anteroposterior direction, have fewer overlying fractures associated with them than unilateral epiduralHematomas, and commonly contain venous blood.

TL;DR: The neurological recovery obtained with this surgical treatment was found to be superior to that reported with postural treatment in which no active attempt is made to define and relieve neural compression.

TL;DR: Twenty-three patients with severe tuberculous meningitis who underwent cerebrospinal fluid shunting within the first month of illness were reviewed nine months later.

TL;DR: Review of aneurysms in this age group by a panel of expert vascular pathologists would resolve the controversy of intracranial berry aneurYSms in infancy.

TL;DR: The utility of two-dimensional, real-time intraoperative ultrasound sector scanning for purposes of tumor localization, tumor biopsy, cyst drainage, and placement of ventricular shunt catheters in 13 patients is demonstrated.

TL;DR: The data provide support for the hypothesis of the mechanism of prolonged cerebral vasospasm and cerebral ischemia associated with subarachnoid hemorrhage, and that systemic heparin may be used with relative safety in patients in whom the aneurysm if protected by partial carotid ligation.

TL;DR: Surgical removal of the lesion followed by chemotherapy combined with irradiation is the treatment of choice in patients with progressive neurological deterioration in whom chemotherapy alone is ineffective.

TL;DR: Histological examination confirmed these lesions to be venous malformations in the cerebellum in 2 patients and in the left frontal region in 1, and arteriovenous malforms in the Cerebellum and right putaminal region in1 patient each.

TL;DR: The predictive values of certain features of computerized tomographic scans in estimating intracranial pressure were investigated in 40 patients following closed head injuries, finding ventricular compression, the size of the parenchymal mass lesion, midline shift, and an intraventricular clot to be suggestive of pressure elevation.

TL;DR: A 4-year-old girl with known coccidioidal meningitis developed posterior fossa signs and CT scanning revealed a large fourth ventricle, which is hypothesized to be a one-way aqueductal valve resulting from the ventricular inflammation.

TL;DR: The Nd:YAG laser has been applied in microneuro-surgery and has been found to be quite effective in removing had and hemorrhagic tumors such as meningiomas, tumors of the deep skull base, or tumors deep in the ventricle.

TL;DR: Effective therapy for eosinophilic granuloma in a single resectable site in the brain appears to be total excision.

TL;DR: In a clinical correlate, postoperative ischemia was presumably prevented in three patients by barbiturate administration and revascularization for unanticipated intracranial vessel occlusion.

TL;DR: Ten patients were treated with systemic administration of mannitol followed by blood substitute (perfluorochemicals) in the acute period of cerebral infarction in order to suppress the development of infarctions and progressive deterioration, and it is thought that this method is applicable in surgical cases in which long-term vascular occlusion is required.

TL;DR: The case is presented of a young boy with a family history of osteogenesis imperfecta tarda who suffered respiratory arrest during hospitalization andRoentgenograms showed severe basilar impression and hydrocephalus.
