Pathologic findings in surgical resections from patients with temporal lobe epilepsy include a wide range of diagnostic possibilities that can be categorized into different groups on the basis of etiology. This paper outlines the various pathologic entities described in temporal lobe epilepsy, including some newly recognized epilepsy-associated tumors, and briefly touch on the recent classifica...
BACKGROUND AND PURPOSE The association of cortical organization disorders with facial hemangiomas or vascular malformations has been described in only a few reports. The purpose of this study was to show the close association of these cutaneous anomalies with cortical dysplasias and intracranial vascular abnormalities. MATERIALS AND METHODS Five patients, all women, with cutaneous vascular ab...
Whole-exome sequencing of two brothers with drug-resistant, early-onset, focal epilepsy secondary to extensive type IIA focal cortical dysplasia identified a paternally inherited, nonsense variant of DEPDC5 (c.C1663T, p.Arg555*). This variant has previously been reported to cause familial focal epilepsy with variable foci in patients with normal brain imaging. Immunostaining of resected brain t...
Epilepsia partialis continua (EPC) is a rare form of focal motor status epilepticus. There is typically a predilection for facial and distal limb involvement, but rarely trunk or abdomen muscles may be affected. Rarely, EPC may also present in association with cortical dysplasia. In this report, we describe the clinical, neuroimaging and ictal electroencephalographic findings of a young woman p...
Schizencephaly is a malformation of cortical development characterized by gray matter-lined clefts in the cerebral cortex and a range of neurological presentations. In some cases, there are features of septo-optic dysplasia concurrently with schizencephaly. The etiologies of both schizencephaly and septo-optic dysplasia are thought to be heterogeneous, but there is evidence that at least some c...
Focal cerebellar cortical dysplasia is an extremely rare disease. The diagnosis could be easily missed on routine computed tomography (CT) and magnetic resonance imaging (MRI) images because the lesion is isodensity on CT images, and isointense to normal gray and white matter on MRI images. Focal distortion of the cerebellar gray-white matter can be found if MRI images are surveyed carefully. H...
The aims of this study were to observe the differential expression of PI3K-AKT pathway-related genes in seizure-inducing brain lesions in type II focal cortical dysplasia, and to explore the relationship between gene expression and histological changes in dysplastic foci and their epileptogenic mechanism. Typical lesions in brain tissue from three patients with epilepsy induced by type II focal...
Altered excitatory synaptic activity is likely a key factor in the neuronal hyperexcitability of developmental cerebral malformations. Using a combined morphologic and molecular approach, we investigated the NMDA receptor and related protein composition in human epileptic patients affected by periventricular nodular heterotopia, subcortical band heterotopia, or focal cortical dysplasia. Our res...
Focal cortical dysplasia is associated with the development of seizures in children and is present in up to 40% of intractable childhood epilepsies. Transcortical freeze lesions in newborn rats reproduce many of the anatomical and physiological characteristics of human cortical dysplasia. Rats with freeze lesions have increased seizure susceptibility and a region of hyperexcitable cortex adjace...
OBJECTIVE The aim of this study was to describe MR findings of osteofibrous dysplasia. MATERIALS AND METHODS MR images of 24 pathologically proven osteofibrous dysplasia cases were retrospectively analyzed for a signal intensity of the lesion, presence of intralesional fat signal, internal hypointense band, multilocular appearance, cortical expansion, intramedullary extension, cystic area, co...
