PURPOSE The method of temporal lobectomy and parietooccipital disconnection has been applied in the treatment of patients with monolateral widespread cortical lesions and with hand motor function intact. There are no data regarding the use of this method in the treatment of patients with bilateral lesions. CASE REPORT A case history of a 15-year-old female patient with medically refractory ep...
BACKGROUND AND PURPOSE HCI is a unique autosomal-dominant sclerosing bone dysplasia affecting the skull base and the calvaria, characterized by cranial nerve deficits due to stenosis of neuroforamina, whereby the mandible is affected to a lesser extent. The aim of this study is to describe the specific radiologic characteristics and course of the disorder. MATERIALS AND METHODS CT scans of af...
BACKGROUND Focal cortical dysplasia (FCD) is the most common cause of intractable epilepsy in children and adolescent. PURPOSE To evaluate the application value of magnetic source imaging (MSI) in treatment of magnetic resonance imaging (MRI)-negative FCD patients with epilepsy. METHODS MSI characteristics of 17 cases of MRI-negative focal cortical dysplasia patients with epilepsy were retr...
BACKGROUND Heterozygous mutations in the chromatin remodeling gene CHD7 cause CHARGE syndrome, a developmental disorder with variable craniofacial dysmorphisms and respiratory difficulties. The molecular etiologies of these malformations are not well understood. Homozygous Chd7 null mice die by E11, whereas Chd7(Gt/+) heterozygous null mice are a viable and excellent model of CHARGE. We explore...
METHODS Thirty-six VLBW infants who underwent F-18 fluorodeoxyglucose (F-18 FDG) brain PET and MRI were prospectively enrolled, while infants with evidence of parenchymal brain injury on MRI were excluded. The regional glucose metabolic ratio and asymmetry index were calculated. The asymmetry index more than 10% (right > left asymmetry) or less than -10% (left > right asymmetry) were defined as...
Cobblestone brain malformation (COB) is a neuronal migration disorder characterized by protrusions of neurons beyond the first cortical layer at the pial surface of the brain. It is usually seen in association with dystroglycanopathy types of congenital muscular dystrophies (CMDs) and ocular abnormalities termed muscle-eye-brain disease. Here we report homozygous deleterious mutations in LAMB1,...
Meckel-Gruber Syndrome (MKS) is an autosomal recessive disorder, characterized by a combination of central nervous system malformation (occipital encephalocele), post-axial polydactyly, and enlarged polycystic kidney dysplasia. With a recurrence risk of 25% this lethal syndrome can be detected in early screening by ultrasound. However, to the authors' knowledge, association of MKS with unilater...
