Prenatal cytomegalovirus disease and cerebral microgyria: evidence for perfusion failure, not disturbance of histogenesis, as the major cause of fetal cytomegalovirus encephalopathy.


From the study of four personal cases of microgyria related to fetal CMV infection and a review of the literature it is concluded that: 1) Microgyria is a frequent neuropathological finding in this disease - 2) CMV microgyria is the result of an insufficiency of cerebral blood supply and is not due to a disturbance of neurogenesis or histogenesis as a consequence of a direct cytopathic effect of the virus on germinal cells. The way by which the CMV causes cerebral ischemia - angeitis or more probably, transient systemic perfusion failure, - is discussed, but remains obscure. Other viruses may act on the fetal brain by way of circulatory disturbances.
