It is usually associated with other brain anomalies. The computed tomographic appearance in nine patients with lissencephaly, representing several separate types and syndromes, is reported. Common manifestations include a smooth cerebral surface and absent opercula that may lend a figure-eight appearance to the brain and smooth subsurface lines that represent abnormal cortical layers or an abnormal white-gray interface.
