Abstract. A newborn baby girl with intracranial extracerebral glioneural (brain) heterotopia in the right frontoparietal area is described. The heterotopic brain was predominantly composed of neuronal and glial elements, with partial cerebellar differentiation. Periventricular nodular heterotopia is a disorder of neuronal migration in which neurons fail to migrate appropriately from the ventricular zone to the cortex during development, resulting in the formation of nodular brain tissue lining the ventricles.

Monosomy 1p36 is the most common subtelomeric chromosomal deletion linked to mental retardation and seizures. Neuroimaging studies suggest that monosomy 1p36 is associated with brain malformations including polymicrogyria and nodular heterotopia, but the histopathology of these lesions is unknown. Here we present postmortem neuropathological findings from a 10 year-old girl with monosomy 1p36 2021-04-11 · When the ongoing process of migration or of the later stage of neuronal migration and cortical organisation are also impaired, subcortical heterotopia or polymicrogyria and schizencephaly may develop with PNH. 4– 13 Lastly, other brain developmental abnormalities such as agenesis of the corpus callosum, hydrocephalus, mega cisterna magna, and cerebellar hypoplasia may also be associated with A brain aneurysm is a weak spot or bulge in a brain blood vessel.

Disruption of these steps yields different types of cortical malformations including gray matter heterotopia, characterized by the ectopic position of neurons along the ventricular walls or in the deep white matter. Heterotopias can occur within the subependymal and periventricular (neural stem cell) zone just overlying the ventricles of the brain, and subcortically just beneath the cortical gray matter. The image below is a hemisphere of a normal adult brain to help you visualize where the different heterotopias may occur. Heterotopia within the brain is often divided into three groups: subependymal heterotopia, focal cortical heterotopia and band heterotopia. Another example is a Meckel's diverticulum , which may contain heterotopic gastric or pancreatic tissue. Disruption of these steps yields different types of cortical malformations including gray matter heterotopia, characterized by the ectopic position of neurons along the ventricular walls or in the deep white matter.

From a clinical perspective, affected patients are best divided into three groups: subependymal, subcortical, and band heterotopia (also called double cortex). CAUTION patients with heterotopia, who have earlier age of seizure onset, may have a change in their seizure types over time, with the emergence of epileptic spasms or generalized seizure types, such as atypical absence, atonic and tonic seizures. Developmental and cognitive impairments are more common in this group. Periventricular nodular heterotopia is a malformation of cortical development due to impaired neuronal migration. Polymicrogyria (PMG) and periventricular nodular heterotopia (PNH) are two developmental brain malformations that have been described independently in multiple syndromes. Clinically, they present with epilepsy and developmental handicaps in both children and adults. Subependymal grey matter heterotopia, also known as periventricular heterotopia, is the most common form of grey matter heterotopia and is characterized by nodules of grey matter located immediately beneath the ependyma of the lateral ventricles.

Individuals with heterotopias show a high incidence of neurological deficits, such as epilepsy.

Refractory epilepsy is present in nearly all affected patients, with partial complex and atypical absence epilepsy being the most common syndromes.
