These include subependymal linear or laminar heterotopia, which are smooth linear regions of heterotopia that line the ependymal wall of the lateral ventricle, and ‘ribbon’ heterotopia (Fig. 7.20), curvilinear undulations of heterotopic gray matter in the deep, periventricular white matter. We report the clinical and mutation spectrum as well as MR imaging for a large cohort of 47 patients with Filamin A associated PVNH including two adult males.

Medical treatment has not proven effective for pancreatic heterotopia and surgical resection is the only curative option. Conclusion. Although pancreatic heterotopia is a rare condition, it should remain in the differential diagnosis for unintentional weight loss and abdominal pain.
Heterotopia occurs when nerve cells (neurons) do not migrate properly during the early development of the fetal brain. Heterotopia means "out of place." In normal brain development, neurons form in the periventricular region, located around fluid-filled cavities (ventricles) near the center of the brain.
Gray matter heterotopia is a neurological disorder that is characterized by the gray matter in the brain being located in the wrong part of the brain. It is associated with epilepsy and can affect higher brain functions and motor skills. Seizures are generally resistant to medication. Common symptoms reported by people with gray matter heterotopia

The clinical and imaging features of gray matter heterotopia: a clinical analysis on 15 patients GMH should also be suspected in patients with juvenile onset of seizures, cognitive decline, and neurological deficits. Magnetic resonance scans may show lesions in the white matter of the brain with signals similar to the normal gray matter. This large family of diseases overlaps with other conditions including ' double cortex syndrome ' or subcortical band heterotopia. More subtle abnormalities such as focal nodular heterotopia and band heterotopia may only be apparent if optimal MRI techniques are used.

The purpose of this study was to perform a morphologic analysis of a series of cases of subcortical heterotopia based on MR images, to METHODS: Between June 2005 and December 2009, the medical records and MRI studies of patients with gray matter heterotopia were reviewed. The MRI morphologic findings of heterotopia were recorded along with the presence and type of associated cranial malformations.
