Publisher Summary Lissencephaly type II is a group of complex brain malformations that anatomically consists of “cobblestone” cortex, abnormal white matter, enlarged ventricles, small brainstem, hypoplastic vermis, and cerebellar polymicrogyria. The spectrum varies from a mild disorganization of the brain layers to severely dysplastic brains.

Ependymal Abnormalities in Lissencephaly/Pachygyria
Journal of Neuropathology and Experimental Neurology, 1993The ependyma was examined in eight children with neuroblast migratory disorders of diverse origin: three cases of lissencephaly type 1 with severe to mild degrees of agyria/pachygyria, four cases of lissencephaly type 2 in Fukuyama muscular dystrophy and the Walker-Warburg syndrome, and one case of hemimegalencephalic pachygyria.

Neuroimaging in lissencephaly type I
Neuroradiology, 1991The CT scan's of 22 patients with lissencephaly type I, a severe developmental disorder of the cerebral cortex, were studied. In 6 patients a magnetic resonance (MR), scan was also performed. The CT and MR scans of the lissencephaly patients were compared to a control group consisting of 49 patients with a normal CT or MR scan.

Lissencephaly with Cerebellar Hypoplasia
2008Abstract Lissencephaly with cerebellar hypoplasia (LCH) is characterized by abnormal development of both the cerebral cortex and cerebellum. LCH is distinguished from classical lissencephaly (Chapter 150) by profound cerebellar hypoplasia and less severe cortical malformations.

Further comments on the lissencephaly syndromes
American Journal of Medical Genetics, 1985Detailed clinical, pathological, and cytogenetic investigations of patients with lissencephaly over the past several years have demonstrated the existence of at least eight distinct conditions with variable genetic implications. In several of these disorders, especially chromosomally normal MDS, ILS, and CCL, too few patients have been reported to ...

AbstractLissencephaly (smooth‐brain) is an abnormality of brain development characterized by incomplete neuronal migration and a smooth cerebral surface. At least 2, and possibly more, distinct pathological types occur, each associated with several distinct syndromes.

Lissencephaly in an adult Australian Kelpie
Australian Veterinary Journal, 2016Case reportA 6‐year‐old neutered male Australian Kelpie presented with a 2‐year history of seizures. Neurological examination was consistent with a generalised prosencephalic lesion. Serum biochemical testing was performed in addition to magnetic resonance imaging of the brain and cerebrospinal fluid analysis.

Publisher Summary Classical or type I lissencephaly are a group of cortical malformations with the common features of cortical thickening and a reduction in gyration. Classical lissencephaly is primarily a disorder of neuroblast migration and is the first of the human cortical malformations for which the genetic basis, and subsequently the molecular ...

Lissencephaly: Computed tomographic diagnosis
Journal of Computed Tomography, 1983Lissencephaly is a rare congenital condition with distinctive brain changes. Most of these changes were demonstrated on computed tomography, and include lack of cortical sulci and gyri; calcification in the region of paraphysis; wide, shallow sylvian fissures; colpocephaly; poor development of white matter; and persistent cavum septum pellucidum and ...

Ocular malformations and lissencephaly
European Journal of Pediatrics, 1987Retinal dysplasia and agyria without cortical lamination are the constant findings in this autosomal recessive syndrome. There may also be anterior chamber malformations, cataract, and microphthalmos. Brain autopsies have shown a variety of associated malformations such as posterior encephalocele, Arnold-Chiari malformation, agenesis of the septum ...
