[Incidence of conspicuous ultrasound findings in the brain in clinically asymptomatic newborn infants].

With an intracranial ultrasound screening at the University Clinic for Obstetrics and Gynaecology Wuerzburg, an abnormal finding was seen in 88 out of 673 clinically asymptomatic usually mature newborns (13.1%). It concerned 37 subependymal/intraventricular haemorrhages (5.5%), sequelae of an old intrauterine bleeding in 9 cases (1.3%), 38 ventricular asymmetries (5.7%), 5 choroidal plexus cysts (0.7%), 6 arachnoidal cysts (0.9%) and 1 infratentorial tumour (0.2%). Only mild cerebral haemorrhages were observed. Follow-up studies of children with an abnormal cerebral finding are desirable to determine its clinical significance and long-term prognosis.
