Patient Data
Age: 30 years
Gender: Male
From the case:
Focal peri-ventricular heterotopia
Loading images...
Axial T1
Focal area of gray matter is seen deeply located and indenting the occipital horn of the left lateral ventricle with adjacent abnormal sulcation of the overlying cortex. A deep sulcus is present which does not appear to reach the ventricle.
Case Discussion
This case demonstrates definite periventricular heterotopia with associated overlying abnormal cortex. The differential is that of closed lip schizencephaly with an unseen cleft reaching the ventricle. The absence of a small nipple-like outpouching from the ependymal surface makes this less likely to be the case.
