Cutis verticis gyrata--mental deficiency syndrome: a patient with drug-resistant epilepsy and polymicrogyria.

ABSTRACT

We report a case of cutis verticis gyrata-mental deficiency syndrome (CVG-MD) which was associated with drug-resistant epilepsy and bilateral occipital polymicrogyria. Genetic analysis showed an increased number of breaks at the 3p14 and 16q23 sites. We hypothesize that a deleterious factor acting at a critical period of intrauterine development could result in the cerebral malformation and in the development of CVG. Neuroradiological investigation is warranted in cases of CVG-MD.
