ABSTRACT
PURPOSE:
To evaluate types of gray matter heterotopias, associated brain anomalies, and its correlation with the patterns of seizure. MATERIALS ANDMETHODS:
We evaluated retrospectively 19 patients(malefemale=109, mean age 21 years) with gray matter heterotopias on brain MRI. Using 1.0T superconducting MR unit, spin echo TI-, proton-density- and T2-weighted images in axial, coronal and sagittal planes were obtained.RESULTS:
Types of gray matter heterotopias were single subependymal in four patients, multiple subependymal in one, focal subcortical in eight, diffuse subcortical in two, mixed multiple subependymal and focal subcortical in four. Associated anomalies were seen in 11 patientsother neuronal migration anomalies in eight patients, corpus callosum agenesis in two, and combined holoprosencephaly and Dandy-Walker malformation in one. Fifteen patients had seizure. The patterns of seizure were not correlated with the types of heterotopias.CONCLUSION:
In addition to subependymal, focal subcortical, and diffuse subcortical types, gray matter heterotopias included mixed variant of of multiple subependymal and subcortical type. Schizencephaly was the most common form of accompanying anomalies, and patterns of seizure were not correlated with types of gray matter heterotopias, even though main clinical menifestation was seizure.
