Abstract

|
Purpose:
@EN To evaluate types of gray matter heterotopias, and its correlation with the patterns of seizure.
@ES Materials and Methods:
@EN We evaluated retrospectively 13 patients(male : female=5 : 8) with gray matter heterotopias on brain MRI, Using 1.5% GE Signa Advantage Unit, spine echo T1-, proton-density and T2-weighted images in axial, coronal and sagittal planes were
obtained.
@ES Results:
@EN Types of gray matter heterotopias were subependymal in seven patients and subcortical in six. Associated anomalies were seen in three patients: other neuronal migration anomalies in two patients, Dandy-Walker malformation in one. Ten patients
had
seizure, but patterns of seizure not correlated with types of heterotopia.
@ES Conclusion:
@EN Gray matter heterotopisa can be classified as suvbependymal and subcortical types. On MRI, heterotopias showed same signal intesity with gray matter in all imaging sequences, and patterns of seizure (main clinical manifestation) were not
correlated
with type of gray matter heterotopia.
