(3) In order to evaluate remyelination in LFB stained sections of cuprizone demyelination of the corpus callosum
in the mice that received progesterone, three blinded readers scored LFB stained sections between zero and three.
Agenesis of the corpus callosum
: A comparison of prenatal ultrasound and magnetic resonance imaging.
abnormalities in psychopathic antisocial individuals.
Interhemispheric cyst associated with partial agenesis of the corpus callosum
. Differential diagnosis includes arachnoid cyst, porencephalic cyst, dermoid/epidermoid cyst, low grade cystic neoplasm (eg, ganglioglioma, DNET), and parasitic cyst (eg, hydatid disease).
The central nervous system symptoms of this syndrome are hypotonia, sensorineural hearing loss and corpus callosum
dysgenesis or agenesis (1,4,7).
of Patients (Percentage) 1) Periventricular leukomalacia 39 (40%) and hypomyelination 2) Malformation of cortical 5 (5.1%) development 3) Corpus callosum
abnormality 42 (43.3%) 4) Diffuse cerebral atrophy, 53 (54.6%) cerebellar atrophy and gliosis 5) Arnold-Chiari and Dandy-Walker 4 (4.1%) syndrome 6) Thalamus and Globus Pallidus 11 (11.1%) lesion 7) Vascular abnormality 1 (1.03%) 8) Perinatal asphyxia changes 87 (89.7%)
abnormalities detected in 4.09 % (n: 9) of the patients.
The corpus callosum
and pericallosal arteries were identified and entry to lateral ventricle was made.
and Gd-enhancing lesions emerged as the most specific, while periventricular and juxtacortical lesions were the most sensitive.
There was also complete regression of hyperintense signal in the corpus callosum
and partial regression in the internal capsules on T2WI and FLAIR.
Splenial lesions may extend into the callosal radiations, frontoparietal subcortical white matter and to the rest of the corpus callosum
. Type I refers to isolated splenial involvement, while type II refers to additional involvement of remainder of the corpus callosum
or supratentorial white matter (4, 5).
the major interhemispheric commisure connects two brain hemispheres .
