Abstract
Based on the published literature and on our own experiences in the imaging of lissencephalies with ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) we propose a strategy for the use of the different methods depending on the clinical symptoms and the age of the patient. In newborns and babies with suspected lissencephaly ultrasound should be used as the first method. If there is a cortical malformation and a more thorough examination seems necessary, CT can be used in type I lissencephaly. However, due to its excellent grey-white matter contrast MRI is the best method for imaging of lissencephalies. Especially in the diagnosis of type II lissencephaly, MRI is definitely superior to CT and US, and so it should be used in all patients with Walker-Warburg syndrome and other congenital muscular dystrophies as well as in all doubtful cases. It must always be remembered that the extent of the cortical dysplasias is quite variable, as is the presence of further malformations.
