Hypothalamic disease in association with dysgenesis of the corpus callosum.
We describe two cases of dysgenesis of the corpus callosum demonstrated by magnetic resonance. The first patient presented with chronic hyponatraemia. Investigation demonstrated re-setting of the osmoreceptor and thirst centres. The calculated threshold for arginine vasopressin (AVP) release was reduced at 252 mosmol/kg while severe thirst was perceived at a plasma osmolality of 260 mosmol/kg. ...
متن کاملFiber Tractography and Diffusion Tensor Imaging in Children with Agenesis and Dysgenesis of Corpus Callosum: A Clinico-Radiological Correlation
Background Corpus callosum is the largest commissure in human brain. It consists of tightly packed white matter tracts connecting the two cerebral hemispheres. In this study we aimed to evaluate role of fiber tractography (FT), and diffusion tensor imaging (DTI) in ped...
متن کاملPeritrigonal and temporo-occipital heterotopia with corpus callosum and cerebellar dysgenesis.
OBJECTIVE To describe a homogeneous subtype of periventricular nodular heterotopia (PNH) as part of a newly defined malformation complex. METHODS Observational study including review of brain MRI and clinical findings of a cohort of 50 patients with PNH in the temporo-occipital horns and trigones, mutation analysis of the FLNA gene, and anatomopathologic study of a fetal brain. RESULTS Ther...
متن کاملClinical, neuroimaging and cytogenetic findings in 20 patients with corpus callosum dysgenesis.
Twenty children with corpus callosum agenesis or hypoplasia were evaluated under a standardized investigation protocol. Psychomotor retardation, seizures, and craniofacial anomalies were the most prominent findings. There were three cases of chromosomal anomalies, all of them representing trisomy of chromosome 8.
متن کاملCorpus callosum dysgenesis limits MRI changes to one hemisphere in status epilepticus.
A 46-year-old man with cerebral palsy presented with complex partial seizures and left sided clonic movements. EEG showed right hemispheric seizures (figure 1). MRI demonstrated dysgenesis of the corpus callosum (figure 2, A and B) with hyperintense signal throughout the right cortex in diffusion-weighted imaging (DWI) (figure 2C) corresponding with decreased apparent diffusion coefficient sign...
