Neurons originate in the germinal matrix adjacent to the ventricules and ultimately migrate outward to form the grey matter of the brain parenchyma. Brain heterotopia. Clin Nucl Med. 2009; 34(3):151-2 (ISSN: 1536-0229) Modarresifar H; Ho L. We present a case with intractable partial complex seizures in a 14-year-old girl who was found to have brain heterotopia on MRI and PET-CT. The patient presented with intractable partial complex seizures and a normal electroencephalogram. Detection of heterotopia generally occurs when a patient receives brain imaging -- usually an MRI or CAT scan -- to diagnosis seizures that are resistant to medication.

FLAIR 2014-09-13 MRI. MRI of the brain demonstrates periventricular (subependymal) grey matter heterotopia best seen bulging into the frontal horn of the right lateral ventricle. Additionally the perisylvian grey matter is thicker than normal with nodular grey-white matter junction.

(Heterotopia means "out of place.") Normally, the neurons that make up the outer surface of the brain (cerebral cortex) are distributed in a well-organized and multi-layered way. Band heterotopia is a congenital disorder that results from the disrupted migration of neurons. Neurons originate in the germinal matrix adjacent to the ventricules and ultimately migrate outward to form the grey matter of the brain parenchyma.

The table shows a dedicated epilepsy protocol. Some will also use Inversion Recovery and not use contrast on a routine base. T1WI Superior for cortical thickness and the interface between grey and white matter.

Patients suffering from this syndrome have been also found to show brain anomalies such as pachygyria, subcortical-band heterotopia (SBH), 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. The neurons then migrate outward to form the exterior of the brain (cerebral cortex) in six onion-like layers. Brain MRI scan; coronal section of a young woman with a missense mutation of the DCX gene. The gyral pattern of the cortex looks normal, but beneath the cortex, and separated from it by a thin layer of white matter, is present a subcortical laminar (band) heterotopia (black arrows) showing the same signal intensity as the cortex.

Whilst grey matter heterotopia may be seen on USS and CT (depending on size), MRI is the imaging of choice for assessing the detail and associated structural abnormalities. MRI should include thin slice volumetric T1-weighted images, axial and coronal T2-weighted and FLAIR images.

Imaging characteristics of periventricular nodular heterotopia: heterotopic nodules of grey matter intensity are seen immediately deep to the ependymal layer, two patterns are seen: Periventricular nodular heterotopia (PNH) is characterized by nodules of heterotopic grey matter located along the walls of the lateral ventricles and can usually be detected using MRI. 2015-10-06 Conti et al. (2013) reported a 7-year-old girl with delayed psychomotor development, delayed speech, strabismus, and onset of seizures with hypsarrhythmia at age 3 months. Brain MRI showed bilateral periventricular nodular heterotopia in the frontal horns.
