title: Diabetic halo.
abstract: In 42 diabetic patients evaluated by ultrasonography in the third trimester of pregnancy, 12 fetuses were found to have the diabetic halo. Of that group, the estimated fetal weight exceeded the 90th percentile in eight of nine studies in which the weight could be estimated sonographically. Overgrowth of the fetal head was not a finding in this group of patients and was not associated with the diabetic halo. The diabetic halo appears to be more accurate than the biparietal diameter as an indicator of infants that are large for gestational age.
