Figure 1. T2w image shows heterotopic gray matter in right centrum semiovale.
Figure 2. FLAIR image coronal section shows heterotopic gray matter in right centrum semiovale.
Figure 3. T1W image shows heterotopic gray matter in right centrum semiovale.
Figure 4. DWI imaging shows no e/o of any restricted diffusion.
Figure 5. T1 contrast image shows no enhancement.
On MRI, the heterotopic tissue follows grey matter on all sequences.
In general, MR spectroscopy demonstrates a decrease in NAA/Cr ratio in the heterotopic grey matter compared to normal control subjects.
On CT, grey matter heterotopia has slightly higher density than the surrounding white matter and can thus be seen if sufficiently large. Thin or small regions may not be apparent.Â
The grey matter heterotopias are a relatively common group of conditions characterized by interruption of normal neuronal migration from near the ventricle to the cortex.
Although heterogeneous, some forms are X linked as such there is an overall predilection.Â
Neuroblasts proliferate in the germinal matrix between seven and eight weeks of gestation.
