Focal pachygyria with unusual vascular anomaly
Neuroradiology, 1990A case of focal pachygyria with an unusual vascular anomaly is reported. Preoperative magnetic resonance imaging demonstrated few and broad gyri, and an abnormally thickened cortex of the right frontal lobe. In addition, T2-weighted imaging showed a high intensity lesion beneath the thickened cortex. In the pachygyric cortex, the peripheral portions of

Acta Neuropathologica, 1975
The architectonic features of abnormal cerebral cortex in a brain with lissencephaly and pachygyria suggest that neuronal migration was interrupted by cortical and subcortical laminar necrosis in the fourth fetal month. The severest cortical abnormality lies in the distal perfusion fields of the major cerebral arteries, while the normal areas are ...

Frontotemporal pachygyria-Two new patients
European Journal of Medical Genetics, 2012We describe two Finnish brothers with frontotemporal pachygyria, intellectual deficiency and mild dysmorphisms. Previously, only a few cases of similar frontotemporal pachygyria have been reported. This report provides further evidence about frontotemporal pachygyria being a distinct genetic entity inherited as an autosomal recessive trait.

Bilateral posterior agyria–pachygyria and epilepsy
Brain and Development, 2003We analyzed the electroclinical findings in two patients with bilateral posterior agyria-pachygyria. Both patients presented with mental retardation, mild motor deficit and epilepsy. The electroclinical findings were characterized by frequent tonic or atonic generalized seizures with occasionally simple or complex partial seizures.

The MR evaluation of pachygyria and associated syndromes
European Journal of Radiology, 1991A retrospective study of 40 children with some form of pachygyria was performed at the Children's Memorial Hospital in Chicago. All 40 children had MR brain scans. We analyzed the MR findings, and correlated these findings with the clinical symptoms and course in all the children. We have autopsy findings in 15% these children.

A new autosomal recessive syndrome of pachygyria
Clinical Genetics, 1996Pachygyria is a rare development disorder resulting from impaired neuronal migration. Usually, it is a sporadic phenomenon, but rare dominant or autosomal recessive syndromes are known. This report describes a family in which the parents are first cousins and three of the siblings suffer from moderate mental retardation, pachygyria and strabismus.

Asymmetric arthrogryposis multiplex congenita with focal pachygyria
Pediatric Neurology, 2001A male infant with predominantly right-sided arthrogryposis multiplex congenita is presented. His posture in the lower extremities was asymmetric, and left thoracic scoliosis was present. This patient also manifested focal pachygyria dominantly affecting the contralateral cerebral hemisphere and hypoplasia of the corpus callosum, brainstem, and ...

[Agyria-pachygyria and pachygyria in children. Contribution of imaging].
Archives de pediatrie : organe officiel de la Societe francaise de pediatrie, 1995Lissencephaly (agyria-pachygyria) is a defect in migration of cerebral neurons resulting in failure of cortical gyri to develop. Progress in imaging techniques improves its diagnosis.The files of 17 patients (ten boys and seven girls), aged 7 months to 16 years, were retrospectively studied.

Lissencephaly-Pachygyria Associated With Congenital Cytomegalovirus Infection
Journal of Child Neurology, 1991We report the presence of major cerebral migrational defects in five severely, multiply handicapped children with congenital cytomegalovirus (CMV) infection. These patients had both computed tomographic (CT) scan and magnetic resonance imaging (MRI) evidence of marked migrational central nervous system defects consistent anatomically with the spectrum
