ependymoma/癲癇性発作

Ependymomas usually arise from the ependymal lining cells of the ventricular system and central canal of the spinal cord. Supratentorial ependymoma is a rare entity with the variable clinical course. In a small number of cases, ependymoma arises from supratentorial parenchyma. Only a few cases are

Tanycytic ependymoma is a rare fibrillary variant of ependymoma with a predilection for the spinal cord. We present an unusual supratentorial subcortical tanycytic ependymoma in a 17-year old male presenting with seizures. Only two other cases of subcortical tanycytic ependymoma have been reported.

A young child presented to the emergency department of a tertiary care hospital with on and off headache, focal seizures involving the left side of the body, weakness of left upper and lower limbs and vomiting for 2 weeks. Examination showed an alert child with grade 4/5 powers in left upper and

BACKGROUND Rasmussen's encephalitis (RE) is a form of chronic encephalitis presenting with intractable seizures and progressive neurological deficits in children. The occurrence of anaplastic ependymoma in a diagnosed case of RE has not been reported in the literature. METHODS We report an eight and

Cortical ependymomas are rare gliomas with classic ependymal features but are unusual in primarily involving the cerebral cortex. Here, we present a 19-year old woman with new-onset seizures who was found to have a large, cortically based non-enhancing lesion with scalloping of the overlying

OBJECTIVE Seizures are common during and after treatment for a primary brain tumor. Our objective was to describe the incidence and risk factors for seizures in long-term survivors of pediatric brain tumors. METHODS In a retrospective, longitudinal study, we reviewed all consecutive patients during

Supratentorial cortical ependymoma is a rare clinical entity where ependymoma occurring in the cortex without any connection to the ventricular system since ependymoma usually arises from the lining of the ventricular system or central canal of spinal cord. There have been 14 such cases reported in

Myxopapillary ependymoma (MPE) is a histological variant of ependymoma found in the conus medullaris or filum terminale region. Intracranial occurrence of the tumor is a rarity. The most characteristic histological feature of myxopapillary tumors is the abundance of intercellular and perivascular

Angiocentric glioma (AG) is a low grade glioma, that was first described in 2002. Since this description, 83 patients with AG have been described, including ours. AG typically presents in childhood with medically refractory seizures that are cured with gross surgical resection. Whilst the natural

A 13-year-old, mixed breed dog presented with a 1-month history of seizures. Magnetic resonance imaging of the brain revealed a 2.2 × 1.0 × 0.9 cm ovoid and elongate cystic mass within the white matter of the left frontal lobe extending caudally from the cribriform plate to the rostral left lateral

BACKGROUND In patients with brain lesions, the appropriate management of epileptic seizures is important because recurrent seizures have a negative effect on the clinical course and quality of life. Acute symptomatic seizures are known to be one of the risk factors to develop epilepsy that cause

We examined potential clinical and pathologic correlates of seizures among the 3,291 children in the Childhood Brain Tumor Consortium database. Fourteen percent had seizures prior to their hospitalization for a brain tumor. Among children who had a supratentorial tumor, seizures occurred in 22% of

Ependymoma is the third most common childhood intracranial tumor after medulloblastoma and pilocytic astrocytoma. Most ependymomas occur in the posterior fossa and spinal cord but only five cases confined to the cerebral cortex have been reported. The current case is a 5-year-old boy with a somewhat
