MR imaging of callosal and corticocallosal dysgenesis.
Callosal dysgenesis implies a malformation of the corpus callosum with origins in the embryogenesis of the telencephalon. A retrospective review of 15 cases of callosal dysgenesis revealed three distinct categories: agenesis (three subjects), hypogenesis (nine subjects), and hypoplasia (three subjects). The basis of this distinction rests upon considerations of neural tube closure, formation an...
متن کاملAbnormal interhemispheric motor interactions in patients with callosal agenesis.
During unilateral hand movements the activity of the contralateral primary motor cortex (cM1) is increased while the activity of the ipsilateral M1 (iM1) is decreased. A potential explanation for this asymmetric activity pattern is transcallosal cM1-to-iM1 inhibitory control. To test this hypothesis, we examined interhemispheric motor inhibition in acallosal patients. We measured fMRI activity ...
متن کاملA Rare Case of Pericallosal-Interhemispheric Lipoma
We are reporting a case of interhemispheric-pericallosal lipoma, associated with bilateral small lateral ventricle choroid plexuses and third ventricle lipoma as well as partial agenesis of splenium of corpus callosum. Presentation in our case does not correspond to existing classification of pericallosal lipoma and as it is very rare, we are presenting it as a case report. Intracranial lipoma ...

متن کاملNeuroplasticity in human callosal dysgenesis: a diffusion tensor imaging study.
Callosal dysgenesis (CD) is observed in many neurodevelopmental conditions, but its subjacent mechanisms are unknown, despite extensive research on animals. Here we employ magnetic resonance diffusion tensor imaging and tractography in human CD to reveal the aberrant circuitry of these brains. We searched particularly for evidence of plasticity. Four main findings are described--1) in the prese...
