Agyria–pachygyria band spectrum

2011
Neuroacanthocytosis syndromes form a genetically heterogeneous group of disorders characterized by the association of neurological abnormalities with acanthocyte. This chapter describes both chorea-acanthocytosis (ChAc) and McLeod syndrome. In the majority of ChAc families, the disease is inherited as an autosomal recessive trait, and is caused by ...

Biological rhythms in patients with lissencephaly (agyria-pachygyria)

Brain and Development, 1993
Lissencephaly is a congenital malformation of the brain characterized by an extensive absence of cerebral gyral formation. Polysomnograms were recorded in 8 cases with lissencephaly (4 of agyria and 4 of pachygyria), and 24-h secretion of growth hormone, prolactin, luteinizing hormone, follicle-stimulating hormone and cortisol was examined in 6 of the ...

Tuberous sclerosis associated with pachygyria

Pediatric Radiology, 1993
The case is presented of a 1.5-year-old with the typical CT features of tuberous sclerosis and pachygyria, in combination. Tuberous sclerosis was evidenced by multiple subependymal calcifications, and pachygyria by the relevant CT appearances. Periventricular heterotopia and total callosal agenesis were associated findings. The findings in this patient

A case with athetosis, mental retardation, deafness, and pachygyria

Brain and Development, 1991
A 6-year-old girl with pachygyria was presented. Regions of pachygiria were seen in the frontal, temporal, and parietal areas in vivo by magnetic resonance imaging. She showed athetosis, mental retardation, deafness, short stature, and microcephalus, but did not show epilepsy.

Brain functional imaging SPECT in agyria-pachygyria

Epilepsy Research, 1996
Agyria-pachygyria or lissencephaly type I, a diffuse cortical malformation, provides infantile spasms (IS) which are refractory and persisting after the first decade, an age at which IS have disappeared in the other causes. In order to study the functional postnatal development of the lissencephalic cortex, we measured regional cerebral blood flow ...

Agyria-pachygyria: clinical, neuroimaging, and neurophysiologic correlations

Pediatric Neurology, 2002
Agyria-pachygyria complex is a disorder of neuronal migration and organization. Patients suffer either motor or intellectual retardation. We report our experiences of 10 patients with agyria-pachygyria complex and evaluate their clinical features, electroencephalography, and evoked potentials.

Sedaghatian spondylometaphyseal dysplasia with pachygyria and absence of the corpus callosum

American Journal of Medical Genetics Part A, 2006
AbstractWe report on a female infant with a metaphyseal dysplasia and a neuronal migration abnormality consistent with a diagnosis of Sedaghatian spondylometaphyseal dysplasia. This child, born to nonconsanguineous Caucasian parents, was hypotonic from birth and experienced recurrent cyanotic episodes within a few hours of delivery.

The agyria-pachygyria complex: A spectrum of cortical malformations

Brain and Development, 1991
Agyria-pachygyria is a relatively common brain malformation in humans as shown by the recent experience with CT scan and MR imaging. However, the specificity of imaging is not completely established and it is not known whether all cases with a thick cortical ribbon and a smooth surface correspond histologically to actual agyria-pachygyria or may belong
