Abstract
The CT scan's of 22 patients with lissencephaly type I, a severe developmental disorder of the cerebral cortex, were studied. In 6 patients a magnetic resonance (MR), scan was also performed. The CT and MR scans of the lissencephaly patients were compared to a control group consisting of 49 patients with a normal CT or MR scan. In lissencephaly the cortical thickness was always larger than 10 mm, as compared to less than 7 mm in the normal situation. In lissencephaly the WSF/DSF index (with/depth of the sylvian fissure) was always larger than 0.29, while in the normal situation less than 0.25.
