Cytomegalovirus infection with lissencephaly.

Lissencephaly is a malformation of the brain in which the brain surface is smooth, rather than convoluted. Among the various causes of lissencephaly, infection by a virus during pregnancy plays an important role. Cytomegalovirus (CMV) is an important pathogen causing this anomaly. We present this case of a young female with 24-week-gestation diagnosed on ultrasound as carrying an anomalous fetus with lissencephalic features. At autopsy, there were multiple intra-nuclear CMV inclusions in the brain and the kidneys. This case is presented for its rarity and for the documentation of the tissue localization of CMV inclusions at autopsy.
