MRI in cerebral developmental malformations and epilepsy.
Cerebral developmental malformations are increasingly recognized as a major cause of developmental delay and epilepsy. The incidence of these developmental malformations in patients with epilepsy is not known, but epilepsy surgery data suggest that this pathology is commonly seen in children who undergo epilepsy surgery for intractable epilepsy. These malformations can be diagnosed by a combination of clinical, neurophysiological, and imaging techniques. However, imaging techniques such as MRI have been able to provide in vivo recognition of many of these malformations and have contributed to the recognition of specific syndromes. These malformations can be classified on an anatomical basis either into diffuse, unilateral, or generalized. However, a combination of imaging data in conjunction with genetics and embryology may be more appropriate in the future. Further technical developments promise to increase the sensitivity of MRI in detecting these malformations and may help to delineate the possible biology of these disorders.
