porencephaly/癲癇性発作

BACKGROUND Seizures are a common problem in small animal neurology and it may be related to underlying diseases. Porencephaly is an extremely rare disorder, and in Veterinary Medicine it affects more often ruminants, with only few reports in dogs. METHODS A one-year-old intact male Shih-Tzu dog was

This case illustrates an uncommon form of symptomatic startle-induced epilepsy associated with infantile hemiplegia. Seizure semiology, neuroimaging and neurophysiological findings support involvement of the supplementary motor area in the generation of this seizure type. We present the case of an

Four autopsy cases of porencephaly and hydranencephaly were evaluated clinico-pathologically. The patients showed profound mental retardation, convulsive seizures and spastic quadriplegia. The life spans were much shorter in the hydranencephalic cases. Pathologically, the cerebral cortex in the

BACKGROUND Clinical and neuroimaging features of patients with epilepsy and coexisting extratemporal porencephaly and hippocampal sclerosis have been previously described. OBJECTIVE To present the clinical characteristics and surgical outcome of 6 patients with intractable epilepsy and coexisting

A 3-year-old boy with West syndrome who was shown to have a cystic lesion on magnetic resonance imagings underwent surgical treatment. He had been initially managed with several antiepileptic drugs, but abnormalities on electroencephalography (EEG) persisted. Histological examination of the cystic

Twenty-six cases of porencephalic cysts were analyzed. The cysts were multiple in 26.9% and were associated with subarachnoid cysts in 11.5%. The main presentations were seizures, cerebral palsy and mental retardation. The unifocal cysts were mainly in the frontoparietal region, suggesting a

BACKGROUND Tubulinopathies include a wide spectrum of disorders ranging from abnormal ocular movement to severe brain malformations, and typically present as diffuse agyria or perisylvian pachygyria with microcephaly, agenesis of the corpus callosum, and cerebellar hypoplasia. They are caused by the

A case of porencephaly in a 33-year-old male is presented. The patient exhibited right hemiparesis and generalized seizures. Computed tomography and, subsequently, craniotomy revealed a cerebral defect in the left parietal lobe, which communicated with the lateral ventricle. On angiography and at

OBJECTIVE To describe repetitive movements of the right arm possibly originating from the ipsilateral SMA area in two drug-resistant epileptic patients. METHODS Two epileptic patients (one female, one male, 35 and 36 years old, respectively) were submitted to pre-surgical evaluation including

The epileptic characteristics and their differences in patients with porencephaly and schizencephaly were, respectively, evaluated. Eleven patients with porencephaly and eight patients with schizencephaly were retrospectively enrolled in this study. Five of the six patients with extensive

OBJECTIVE We evaluated the results of cortical resection of epileptogenic tissue for treatment of intractable porencephaly-related epilepsy. METHODS We examined clinical features, electrophysiological data, surgical findings, and seizure outcomes after cortical resection in eight patients with

Prothrombotic conditions are known risk factors for porencephalic cyst formation and cerebral vein thrombosis. Intracerebral hemorrhage is a potential complication of a cerebral vein thrombosis. Porencephaly is a risk factor for intracerebral hemorrhage and cerebral vein thrombosis formation. We

Porencephaly is the congenital cerebral defect and a rare malformation and described few MRI reports in veterinary medicine. MRI features of porencephaly are recognized the coexistence with the unilateral/bilateral hippocampal atrophy, caused by the seizure symptoms in human medicine. We studied 2

BACKGROUND Functional hemispherectomy is a well-established method in childhood epilepsy surgery with only a few reports on its application in adults. METHODS We report on 27 patients (median age 30 years, range 19-55) with a follow-up of more than 1 year (median 124 months, range 13-234). Etiology
