meningioma/癲癇性発作

Meningioangiomatosis is regarded as a rare, benign, hamartomatous malformation. Histopathologically, the lesion is characterized by circumscribed transcortical and leptomeningeal meningovascular proliferation with focal calcifications. It may be classified into cases with predominant cellular or

OBJECTIVE Prolongation of the cortical silent period (CSP) following transcranial magnetic stimulation has been reported in patients with partial epilepsy involving the primary motor cortex (M1). This study aimed to investigate the relationship between the expected intraindividual variations in risk

We analyzed the incidence of postoperative seizures in patients undergoing craniotomy for meningioma removal in order to determine whether EEG recordings are able to predict the incidence of postoperative seizures. We included 102 patients who had undergone surgery on intracranial meningiomas. Pre-

A 37-year-old female presented with medically intractable complex partial seizures with secondary generalization. She was found to have a dural-based lesion with radiologic features of meningioma. A gross total resection was performed and pathology confirmed a diagnosis of cavernous angioma and she

Introduction: No formal indication currently exists for seizure prophylaxis in neurosurgical oncology patients. Neither have specific recommendations been made on the use of antiepileptic drugs (AED) in seizure-free patients with

The aim of the present study was to identify the major factors correlated with early postoperative seizures in elderly patients who had undergone a meningioma resection, and subsequently, to develop a logistic regression equation for assessing the seizures risk. Fourteen factors possibly correlated

BACKGROUND Partial olfactory seizures are infrequent. They are related to the presence of lesions in the uncinate area of the temporal lobe. Patients describe smells during the ictal phase that are generally unpleasant. We report the cases of two patients with olfactory disorders of a paroxysmal

In a study of a consecutive series of 127 surgically treated meningiomas, it was found that 29% of the patients had reported with convulsions as their initial symptom. In this group, surgical excision of the meningioma stopped the convulsions in about half of the patients, but the others continued

The authors have assessed the incidence of postoperative seizures in 158 patients with supratentorial meningiomas diagnosed by computerized tomography (CT) and/or magnetic resonance (MR) imaging, which theoretically should lead to early diagnosis and treatment and the potential for improved seizure

BACKGROUND Epilepsy is a major cause of morbidity and mortality in meningioma patients. The aims of this study were to determine which factors predispose meningioma patients to developing perioperative seizures and to understand the impact of antiepileptic drugs. METHODS Patients treated for a

BACKGROUND Seizures are a common manifestation of brain tumors, but literature on the incidence of seizures before and after surgery for meningiomas is limited, and principles for use of antiepileptic drugs (AEDs) are controversial. METHODS This review is based on a MEDLINE search for articles from

OBJECTIVE To identify variables associated with the development of pre- and postoperative seizures in patients who underwent surgical resection of intracranial meningiomas, in a patient cohort not routinely treated prophylactically with antiepileptic drugs (AED). METHODS Retrospective cohort study

Seizures in rare atypical and malignant meningiomas were significantly under-studied. Our aim was to examine the rates, predictors, and seizure control in these meningiomas, and to analyze associations between clinical characteristics and seizure free survival (SFS) following surgical resection in

OBJECTIVE Well-defined risk factors for the identification of patients with meningioma who might benefit from preoperative or early postoperative seizure prophylaxis are unknown. We investigated and quantified risk factors to determine individual risks of seizure occurrence in patients with
