Brain tumor seizure

Samuel Lapalme-Remis, Gregory D Cascino
PURPOSE OF REVIEW: This article discusses structural and functional neuroimaging findings in patients with seizures and epilepsy. The indications for neuroimaging in these patients and the potential diagnostic utility of these studies are presented. RECENT FINDINGS: Patients presenting with new seizures typically require urgent imaging to rule out a critical underlying cause. MRI is the structural neuroimaging procedure of choice in individuals with epilepsy. Specific epilepsy protocols should be considered to increase the diagnostic yield of neuroimaging in patients with structural lesions associated with focal or generalized seizures...

Tuberous sclerosis complex (TSC) is an autosomal dominant and multi-system genetic disorder in humans. TSC affects around 25,000 to 40,000 individuals in the United States and about 1 to 2 million individuals worldwide, with an estimated prevalence of one in 6,000 newborns. TSC occurs in all races and ethnic groups, and in both genders. TSC is caused by defects or mutations in two genes, TSC1 and TSC2. Loss of TSC1/TSC2 leads to dysregulation of mTOR, resulting in aberrant cell differentiation and development, and abnormal enlargement of cells...

OBJECTIVE Laser ablation is a novel, minimally invasive procedure that utilizes MRI-guided thermal energy to treat epileptogenic and other brain lesions. In addition to treatment of mesial temporal lobe epilepsy, laser ablation is increasingly being used to target deep or inoperable lesions, including hypothalamic hamartoma (HH), subependymal giant cell astrocytoma (SEGA), and exophytic intrinsic hypothalamic/third ventricular tumors. The authors reviewed their early institutional experience with these patients to characterize clinical outcomes in patients undergoing this procedure...

INTRODUCTION: Cerebral venous sinus thrombosis (CVST) is a rare condition with the potential to cause severe morbidity and mortality. CVST can also occur after vestibular schwannoma (VS) surgery with the thrombosis of transverse and sigmoid sinus. However, there is not a single report of superior sagittal sinus (SSS) thrombosis after VS surgery reported in the literature. CASE REPORT: A 45-year-old lady presented to our centre with large left sided solid cystic VS...

The limited ability for injured adult axons to regenerate is a major cause for limited functional recovery after injury to the nervous system, motivating numerous efforts to uncover mechanisms capable of enhancing regeneration potential. One promising strategy involves deletion or knockdown of the phosphatase and tensin (PTEN) gene. Conditional genetic deletion of PTEN before, immediately following, or several months after spinal cord injury enables neurons of the corticospinal tract (CST) to regenerate their axons across the lesion, which is accompanied by enhanced recovery of skilled voluntary motor functions mediated by the CST...

Patients with low-grade glioma frequently have brain tumor-related epilepsy, which is more common than in patients with high-grade glioma. Treatment for tumor-associated epilepsy usually comprises a combination of surgery, anti-epileptic drugs (AEDs), chemotherapy, and radiotherapy. Response to tumor-directed treatment is measured primarily by overall survival and progression-free survival. However, seizure frequency has been observed to respond to tumor-directed treatment with chemotherapy or radiotherapy...

Epileptic seizures, the most common symptom accompanying glioma, are closely associated with tumor growth and patient quality of life. However, the association between glioma and glioma-related epilepsy is poorly understood. In fact, findings related to the location of epileptogenicity have been inconsistent in previous studies. We investigated seizure foci in patients with glioma and the corresponding association between glioma-related epilepsy and the tumoral and peritumoral microenvironment. Clinical characteristics, extracellular electrophysiology, immunohistochemistry, and western blots were conducted on 12 patients with glioma; nine patients had histories of preoperative seizures while three did not...

Although neurological features are commonly encountered in Whipple's disease (WD), presentation with purely neurologic patterns is uncommon. Exclusive confinement to the central nervous system (CNS) is extremely rare. In these cases, the development of isolated cerebral mass is exceptional. In the present paper, the authors describe a case of a 68-year-old man who presented with partial seizures. The neurological examination was normal. The imaging showed a cystic lesion. This tumor-like lesion was removed by performing frontal craniotomy...

BACKGROUND: Timely diagnosis of meningeal carcinomatosis is often difficult even with the assistant of magnetic resonance imaging examination, cerebrospinal fluid analysis, or both. To the best of our knowledge, gadobutrol-enhanced MRI has not been reported in the diagnosis of meningeal carcinomatosis. Here we present two cases where meningeal carcinomatosis was identified on gadobutrol-enhanced magnetic resonance imaging. CASE PRESENTATION: We identified two cases of meningeal carcinomatosis who had been diagnosed with malignant tumors several years ago...

Granule cell dispersion (GCD) in the dentate gyrus (DG) of the hippocampus is a morphological alteration characteristic of temporal lobe epilepsy. Recently, we reported that treatment with naringin, a flavonoid found in grapefruit and citrus fruits, reduced spontaneous recurrent seizures by inhibiting kainic acid (KA)-induced GCD and neuronal cell death in mouse hippocampus, suggesting that naringin might have beneficial effects for preventing epileptic events in the adult brain. However, it is still unclear whether the beneficial effects of naringin treatment are mediated by the metabolism of naringin into naringenin in the KA-treated hippocampus...

Autoimmune encephalitis, an inflammatory disease of the brain, is usually attributed to antibody-mediated damage and dysfunction of neuronal structures. A distinction is made between onconeuronal antibodies (directed against intracellular neuronal antigens with resulting paraneoplastic neurological syndromes) and antibodies directed against neuronal cell surface proteins (with resulting synaptic encephalopathies). Anti-NMDA-Receptor-Encephalitis, the most common form of autoimmune encephalopathy, is characterized by a phased course of disease...

The change in the therapeutic targets from neuron to glia has proved beneficial in the treatment of many psychiatric disorders. The anti-epileptic drugs (AEDs) have been widely prescribed for the treatment of partial and complete seizures, bipolar disorder among others. The current study was carried out to explore the efficacy of some conventional and novel AEDs for the treatment of tumor-associated epilepsy which develops in 29-49% of the patients diagnosed with brain tumors. We used C6 glioma cell line as model system to study the effect of selected AEDs, viz...

Glioblastoma Multiforme (GBM) is the most common form of primary brain tumor with 30-50% of patients presenting with epilepsy. These tumor-associated seizures are often resistant to traditional antiepileptic drug treatment and persist after tumor resection. This suggests that changes in the peritumoral tissue underpin epileptogenesis. It is known that glioma cells extrude pathological concentrations of glutamate which is thought to play a role in tumor progression and the development of epilepsy. Given that pathological concentrations of glutamate have been shown to dephosphorylate and downregulate the potassium chloride cotransporter KCC2, we hypothesized that glioma-induced alterations in KCC2 in the peritumoral region may play a role in tumor-associated epilepsy...
