Unilateral polymicrogyria. Unilateral polymicrogyria. (A) Axial slice shows inward folding in the right central region. The cortex displays nodular, bumpy appearance. Note also absent septum pellucidum and septum cavum vergae. The sylvian fissure, better demonstrated in the sagittal image (B), is lined by polymicrogyric cortex, extending upward toward the interhemispheric fissure. Photograph courtesy of Alexandre Bastos.
