Discussion Heterotopias comprise a complex and wide spectrum of abnormalities,
characterized by the presence of islands of gray matter located outside the cortex or the …

BACKGROUND AND PURPOSE: Gray matter heterotopia have been divided into three
groups based on clinical and imaging characteristics: subependymal, subcortical, and band …

We report unusual MRI patterns in patients with grey matter heterotopia. Standard T1-and T2-
weighted spin-echo and inversion-recovery sequences were used in 22 patients presenting …

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 …

The “band heterotopia” or “double cortex” is a brain anomaly that is presumed to result from
a premature arrest of neuronal migration. Patients with this anomaly are reported to have a …

The authors describe the case of an 11-year-old boy with a neuroradiologic pattern of band
gray matter heterotopia, clinically characterized by epileptic seizures as well as normal …

Magnetic resonance (MR) images and clinical records of 20 patients with gray matter
heterotopias were retrospectively reviewed to correlate MR characteristics of the …

Heterotopia of the gray matter is a developmental malformation in which ectopic cortex is
found in the white matter of the brain. A case of a 33-year-old man with cortical heterotopia …

Heterotopias are conglomerates of neurons and glial cells in an abnormal location and
belong to a group of malformations, which are the result of a disturbed migration of neurons …

AIM: To evaluate magnetic resonance imaging (MRI) features of different types of gray
matter heterotopia. METHODS: Between June 2005 and December 2009, the medical …
