Abstract
|
|
|
Neuronal migrational anomalies are rare congenital malformations of the brain, and caused by interruption of normal migration of neuroblasts during the 2nd to 6th months of gestation. These anomalies include agyria/pachygyria complex, schizencephaly, heterotopia of gray matter, polymicrogyria.
Six patients with migrational anomalies are evaluated by MRI. One patient has agyria/pachygyria complex anomaly, three patients have schizenceaphaly, and two patients have gray matter heterotopia.
The patients have other associated anomalities, such as absence of septum pellucidum, and some have complex anomalies.
MRI is better method to determine the migratory disorders than CT, because of better contrast between gray and white matter, and multiplanar capability of MRI. MRI is an excellent method for diagnosing these neuronal migrational anomalies.
