OBJECTIVE: The objective of the study was to identify a cerebral ultrasound finding indicative of fetal cytomegalovirus (CMV) infection at midgestation. STUDY DESIGN: All fetuses of 218 patients with primary CMV infection underwent prospective transvaginal neurosonographic examination at 20-22 weeks' gestation. RESULTS: Transvaginal sonography identified a periventricular echogenic halo with well-defined borders in 6 infected fetuses at a mean gestational age of 20.5 weeks. Transabdominal axial views of the fetal head were normal in all cases. All patients opted for termination of pregnancy. Autopsy in 2 fetuses showed changes compatible with subacute white matter injury resembling telencephalic leukomalacia. CONCLUSION: A fetal cerebral periventricular halo disclosed by transvaginal sonography at midgestation in pregnant patients with recent CMV infection is suggestive of fetal infection and may be associated with white matter lesions.
