MRI of perisylvian polymicrogyria and open lip schizencephaly
Coronal and axial T1 (above) and axial T2 (below) MRI without contrast of the brain shows small haphazard appearing gyri and too few sulci present bilaterally, left greater than right, primarily in the sylvian fissures. There is also a cleft of gray matter with cerebrospinal fluid within extending from the cortex to the posterior aspect of the left lateral ventricle.

The diagnosis was bilateral perisylvian polymicrogyria in a patient with left open lip schizencephaly.
