Infant with meningomyelocele who has had a VP shunt placed

MRI of heterotopia
Axial (left) and coronal (right) T2 MRI without contrast of the brain shows multiple subependymal nodules along the lateral wall of the left lateral ventricle that have signal characteristics similar to those of gray matter. Similar lesions were found in the right lateral ventricle on images that did not contain artifact from the right parietal VP shunt.

The diagnosis was heterotopia.
